TPS5430DDAR is a 3 A step-down switching regulator from Texas Instruments in an 8-pin SO PowerPAD package, for distributed power architectures — point-of-load rails derived from a higher-voltage bus. Its advantage over linear regulation is efficiency: at 3 A output, a switcher wastes far less power as heat, which shrinks heatsinking and improves system reliability. Selection advice: the DDA suffix denotes the thermally enhanced PowerPAD package and R tape-and-reel packing — thermal performance depends on the PowerPAD soldered to copper, so follow the datasheet layout guidance. Switching regulators need their inductor and compensation network designed around the chip; confirm your input/output voltage and current requirements against the datasheet before substituting a different regulator. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

LM2596S-ADJ/NOPB is a Texas Instruments SIMPLE SWITCHER 3 A step-down regulator in TO-263-5 (DDPAK), tube — for general-purpose buck conversion: appliances, industrial power and pre-regulation. 3 A switching with only a handful of external components is the selection point: the classic easy-to-design buck. Selection advice: the S suffix denotes the TO-263 surface-mount package — for through-hole, the TO-220 LM2596T variants are the siblings; ADJ is the adjustable 1.2 V to 37 V version — for fixed 3.3 V, 5 V or 12 V rails, the fixed versions need no feedback divider; the 150 kHz switching keeps design simple but needs a larger inductor than modern MHz bucks — pick it for simplicity and proven supply, not for smallest size. 4.5 V to 40 V input. TI lists this part as ACTIVE. Parameters verified against the TI official product page. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TPS62160DSGR is a Texas Instruments DCS-Control synchronous step-down converter in 2 x 2 mm WSON-8, tape and reel — for high-density power rails: battery systems and 12 V intermediate rails. 2.25 MHz switching with 17 µA quiescent current is the selection point: tiny inductors plus high light-load efficiency. Selection advice: the DSGR suffix denotes the 2 x 2 mm WSON-8 package — for the 3 x 3 mm VSSOP-8, the DGK variants are the siblings; TI documents pin-to-pin compatibility with the TPS62170 and TPS62125 — verify against the datasheet before substituting; the adjustable 0.9 V to 6 V version suits non-standard rails, fixed versions exist for standard rails. 3 V to 17 V input, up to 1 A output. TI lists this part as ACTIVE. Parameters verified against the TI official product page. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TPS7A4901DGNR is a Texas Instruments 36 V, 150 mA ultra-low-noise positive linear regulator in MSOP-8 PowerPAD, tape and reel — for clean analog rails: op amps, ADCs, DACs and precision instrumentation. 12.7 µVRMS noise with 72 dB PSRR is the selection point: post-DC/DC ripple filtering for noise-sensitive circuits. Selection advice: the DGNR suffix denotes MSOP-8 PowerPAD in tape and reel — the adjustable 1.194 V to 33 V version; the negative-rail complement is the TPS7A3001 — for bipolar analog supplies, pair them; the enable pin plus capacitor-programmable soft start suit sequenced rails. 3 V to 36 V input. TI lists this part as ACTIVE. Parameters verified against TI documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

AP2112K-3.3TRG1 is a 3.3 V low-dropout regulator from Diodes Incorporated in a SOT-25 package — for portable and embedded products. The tiny SOT-25 footprint is the selection point: a complete 3.3 V rail in minimal board area for space-constrained designs. Selection advice: the TRG1 suffix denotes the tape-and-reel packing configuration — match the full code. As an LDO, verify your input-to-output differential and load current against thermal limits of the small package; for higher currents or larger differentials, step up to a larger-package LDO or a switching regulator. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

MCP1700T-3302E/TT is a Microchip 3.3 V fixed low-dropout regulator in SOT-23-3, tape and reel — for battery-powered 3.3 V rails: sensors, MCUs and smoke/CO detectors. 1.6 µA quiescent current with 178 mV dropout at 250 mA is the selection point: minimal battery drain in sleep plus low headroom. Selection advice: the 3302 code denotes the 3.3 V fixed output — the MCP1700 family covers 1.2 V to 5.0 V fixed options, match the code to your rail; the T suffix denotes tape and reel; 250 mA suits light loads — for heavier loads or adjustable output, step up to a larger LDO family. 2.3 V to 6 V input. Microchip lists this part as Active. Parameters verified against distributor and manufacturer documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

LM317T/NOPB is a Texas Instruments LM317-N adjustable positive linear regulator in TO-220-3, for bench supplies, lab equipment and industrial control rails where a rugged, forgiving regulator matters more than efficiency. 1.25 V to 37 V output set by two external resistors, with current limit, thermal overload and safe-area protection, is the selection point: this is the regulator designers reach for when the load may be abused. Its floating topology is a quiet second advantage — the chip sees only the input-output differential, so it can regulate rails stacked on high-voltage supplies where fixed regulators cannot. Selection advice: the T suffix denotes the TO-220 through-hole package — at 1.5 A with a large input-output differential the dissipation is significant, so plan a heatsink; NOPB denotes the lead-free finish. For 500 mA or 100 mA loads the LM317M and LM317L variants run cooler and smaller; for 3 A or 5 A rails step up to the LM150 or LM138 series. TI lists this part as Active. Parameters verified against the TI official product page. Note: this code belongs to TI's legacy LM317-N family — TI's product page points new designs to the drop-in LM317 (new chip) family (e.g., LM317KTTR); do not substitute a new-chip TO-220 code without checking the full orderable. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

MC34063ADR2G is an onsemi MC34063A-series buck/boost/inverting switching regulator in SOIC-8, tape and reel — for cost-sensitive auxiliary rails, LED drivers and legacy industrial boards where one jelly-bean part must cover step-up, step-down or inverting topologies. 3 V to 40 V input, adjustable 1.25 V to 40 V output and a 1.5 A internal switch is the selection point: one BOM line that adapts to whatever rail the board needs. Selection advice: the D suffix denotes SOIC-8 for SMT assembly; R2G denotes tape and reel. The 1.5 A rating is the switch current, not the output current — in boost and inverting topologies the available output current is lower, so size the inductor and diode for your topology rather than the headline number. This is a non-synchronous part: cheaper and simpler than modern synchronous bucks, but less efficient — for battery-powered designs, compare it against a synchronous alternative. If you only need step-down at higher current, the TI LM2596S-ADJ/NOPB (3 A, 150 kHz buck) on this site is the proven larger sibling; if you need boost or inverting, the MC34063A remains the flexible choice. Commercial 0 °C to 70 °C grade — for automotive temperature and qualification, ask about the onsemi NCV-prefixed series. onsemi lists this part as Active. Parameters verified against distributor and manufacturer documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

UCC27211DDA is a Texas Instruments 120 V half-bridge gate driver in 8-pin SO PowerPAD, tube — for telecom, server and industrial power supplies driving high-side and low-side MOSFETs in half-bridge and full-bridge topologies. 4 A source and 4 A sink with 18 ns propagation delay is the selection point: hard-switching large MOSFET gates without the shoot-through that weaker drivers invite. Selection advice: this is a dual-independent-input part — HI and LI are driven separately and there is no enable pin, so dead time must be enforced by your controller, not the driver. The DDA package thermal pad must be soldered to a ground plane; without it the 4 A peaks overheat the package. Lifecycle note: distributors disagree on this part — DigiKey flags it Obsolete while other channels still list it Active — so treat it as legacy stock: confirm date code and traceability, and state any lifetime-buy quantity in your RFQ. Parameters verified against TI datasheet documentation. We reconfirm the offered lot before quotation and reply within 24 hours.

DRV8833PWPR is a Texas Instruments dual H-bridge motor driver in HTSSOP-16 PowerPAD, tape and reel — for battery-powered robots, printers and consumer devices driving two DC motors or one bipolar stepper from a single chip. 1.5 A RMS (2 A peak) per bridge over a 2.7 V to 10.8 V supply is the selection point: it runs directly from a single Li-ion cell or a 5 V rail with no extra power stage. Selection advice: the PWP suffix denotes the thermally enhanced HTSSOP-16 — solder the exposed pad to a copper pour, because at 1.5 A the package relies on the board for cooling; R denotes tape and reel. The two bridges can be paralleled to drive one higher-current motor, often cheaper than moving to a larger driver — but stay within the datasheet paralleling guidance. For higher voltage or current rails, look upward within the TI DRV driver family rather than paralleling beyond the datasheet limits. TI lists this part as Active. Parameters verified against the TI official product page. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

DRV8825PWPR is a Texas Instruments microstepping bipolar stepper motor driver in HTSSOP-28 PowerPAD, tape and reel — for 3D printers, scanners and office automation driving one bipolar stepper with smooth, quiet motion. 8.2 V to 45 V supply with up to 2.5 A per coil and 1/32 microstepping is the selection point: high-voltage headroom plus fine microstepping from a simple STEP/DIR interface. Selection advice: the PWP suffix denotes the thermally enhanced HTSSOP-28 — solder the exposed pad to copper, because 2.5 A is only reachable with proper heatsinking; R denotes tape and reel. Against the Allegro A4988 on this site (35 V, 2 A, 1/16 step): pick the DRV8825 for higher voltage, higher current and finer microstepping; pick the A4988 for lower cost at modest power. Built-in overcurrent, thermal shutdown and undervoltage lockout plus the nFAULT pin simplify fault handling. TI lists this part as Active. Parameters verified against the TI official product page. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

DRV8871DDAR is a brushed DC motor driver from Texas Instruments in an 8-pin SOIC package, with integrated current regulation — for small brushed-DC motors in appliances, toys and automation. Integrated current regulation is the selection point over basic H-bridges: it limits motor current without external sense resistors and comparators, protecting both the motor and the driver. Selection advice: the DDAR suffix denotes SOIC-8 on tape and reel — match the full code to your layout. Confirm your motor voltage and stall current against the datasheet ratings before substituting a different driver. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

A4988SETTR-T is an Allegro MicroSystems DMOS microstepping stepper motor driver in QFN-28, tape and reel — for 3D printers, CNC machines and consumer motion control where a proven low-cost stepper driver matters. Built-in translator with full-step down to 1/16 microstepping, 35 V and ±2 A drive is the selection point: one STEP pulse equals one microstep, no phase tables to program. Selection advice: the SETTR-T suffix denotes the QFN-28 package in tape and reel; the SET temperature grade covers −20 °C to +85 °C. Against the TI DRV8825 on this site (45 V, 2.5 A, 1/32 step): the A4988 costs less and is the 3D-printing classic, but tops out at 1/16 microstepping and lower voltage — pick it when the motor fits within 35 V and 2 A. Synchronous rectification keeps dissipation low; thermal shutdown and short-circuit protections are built in. On 3D-printer StepStick-style modules the A4988 and DRV8825 footprints are largely interchangeable — but check driver orientation, microstepping jumpers and current setting before swapping, as the two parts differ. Parameters verified against distributor and manufacturer documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

L298N is a dual full-bridge driver from STMicroelectronics in a Multiwatt-15 package — for DC and stepper motors. This is the classic motor driver that launched a thousand Arduino robot kits: two full bridges with separate enable inputs in one package, an operating supply up to 46 V and total DC current up to 4 A across both bridges combined, with a separate logic-supply pin. Selection advice: the L298 is a bipolar Darlington design with significant saturation voltage drop — at higher currents it runs hot and wastes power, so modern MOSFET-based drivers (like the TB6612FNG) are more efficient for battery applications. Choose the L298N where simplicity and ruggedness matter more than efficiency, and plan heatsinking for the Multiwatt package. The L298 contains no clamp diodes — budget external fast-recovery freewheeling diodes per bridge (the L293D integrates them; the L298 does not). State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TPS54331DR is a 3 A synchronous step-down converter from Texas Instruments in an 8-pin SOIC package — for industrial power supplies. Synchronous rectification is the selection point over nonsynchronous bucks: the integrated low-side MOSFET replaces the external Schottky diode, raising efficiency and cutting component count. Selection advice: the DR suffix denotes SOIC-8 on tape and reel — match the full code to your layout. Confirm your input/output voltage and load current against the datasheet, and follow the layout guidance for the switching node. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TPS54202DDCR is a Texas Instruments 2 A synchronous buck converter in SOT-23-6, tape and reel — for 12 V and 24 V distributed rails: white goods, STB/DTV and printers stepping down to 5 V or 3.3 V. 4.5 V to 28 V input with integrated MOSFETs and internal compensation is the selection point: a complete 2 A rail in a 6-pin package with minimal externals. Selection advice: the R suffix denotes tape and reel; for the 1 A sibling, the TPS54201DDCR is the counterpart. Eco-mode maximizes light-load efficiency and spread-spectrum switching eases EMI — useful where the converter sits near noise-sensitive circuits. Fixed 500 kHz. Parameters verified against TI documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TPS54620RGYR is a Texas Instruments synchronous buck converter with integrated MOSFETs in VQFN-14, on tape and reel — for point-of-load power in networking, industrial and FPGA rails, with an adjustable switching frequency, external-clock synchronization, Power Good and soft-start tracking for rail sequencing. Selection advice: the RGYR suffix denotes the 14-pin VQFN in tape and reel — for a smaller current class in SOT-23-6, the TPS54202DDCR on this site is the smaller counterpart. TI lists the orderable as Active in its package option addendum; the electrical rows, including the MOSFET on-resistances at their stated gate-drive conditions, are in the parameter table. Parameters verified against Texas Instruments documentation (SLVS949F). State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TPS1H100BQPWPRQ1 is a Texas Instruments single-channel high-side switch in 14-pin HTSSOP, tape and reel — for automotive load driving: relays, lamps and resistive loads switched from the high side. AEC-Q100 qualification with 4 A, 80 milliohm N-channel FET and 5 V to 40 V load range is the selection point: an automotive-grade protected switch, not a bare MOSFET. Selection advice: the Q1 suffix denotes the automotive-qualified grade — for the non-automotive version, check the non-Q1 ordering code. Adjustable current limiting, open-load detection and thermal shutdown with a status flag simplify diagnostics; the R suffix denotes tape and reel. −40 °C to +125 °C. TI lists this part as Active through distribution. Parameters verified against TI documentation and distributor listings. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TPS7B6950QDBVRQ1 is a Texas Instruments automotive 5 V fixed LDO regulator, 150 mA output, up to 40 V input, AEC-Q100 qualified, in SOT-23-5 — the off-battery 5 V rail for automotive MCUs, CAN transceivers and sensors. The AEC-Q100 qualification with -40 to +150 °C junction temperature is the selection point: it survives load-dump-adjacent transients and under-hood heat that disqualify catalog-grade LDOs. Selection advice: dropout is 0.8 V maximum at 100 mA, so the input must stay above roughly 5.8 V at full load — verify cranking-profile compatibility if this feeds from the battery rail directly. The 25 µA quiescent current suits always-on keep-alive rails; for higher-current 5 V rails compare the TPS7B69xx higher-current siblings rather than paralleling. The DBV suffix is the SOT-23-5 package, R = tape and reel. Parameters verified against the TI TPS7B69-Q1 datasheet and DigiKey listings. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TLC6C5712QPWPRQ1 is a Texas Instruments 12-channel constant-current-sink LED driver with full diagnostics for automotive cluster and panel lighting, supplied in the HTSSOP-28 PowerPAD package (PWP) on a large tape-and-reel carrier. Its dot correction is 8-bit per channel — the 12 in the device name is the channel count, a distinction worth enforcing because even TI’s own PDF metadata confuses the two. The channel current is set by a single external reference resistor, and the conditioned ratings (current, dropout, accuracy) are stated with their datasheet test conditions in the parameter table. Selection advice: confirm the current set-point and the reference resistor with engineering before ordering, and confirm the AEC-Q100 Grade 1 qualification is required before accepting a non-Q1 substitute. Parameters verified against the TI TLC6C5712-Q1 datasheet SLVSCO9A (Rev. A). State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

LD1086DT33TR is an STMicroelectronics 3.3 V fixed LDO regulator in TO-252 (DPAK), tape and reel — for 1.5 A rails from high-voltage inputs: industrial 24 V systems and automotive modules stepping down to 3.3 V logic. AEC-Q100 qualification with 6.3 V to 30 V input and 1.3 V dropout is the selection point: an automotive-grade 1.5 A LDO that tolerates the 24 V rail. Selection advice: the TR suffix denotes tape and reel; against the ADP151AUJZ-3.3-R7 on this site — the LD1086 is the 1.5 A workhorse for higher-current rails, while the ADP151 is the 200 mA ultralow-noise part for RF and precision analog. Only 10 microfarad minimum output capacitance for stability. −40 °C to +125 °C. Parameters verified against distributor and manufacturer documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

AMS1117-3.3 is a 3.3 V, 1 A low-dropout linear regulator in a SOT-223 package, for general-purpose power rails in embedded and consumer designs. Its advantage is simplicity: a fixed 3.3 V output with minimal external components, which keeps power-tree cost and design effort low where efficiency is not the binding constraint. Selection advice: the -3.3 suffix fixes the output voltage — the AMS1117 family also ships in adjustable and other fixed-voltage versions that are not interchangeable, so match the full code. As a linear regulator it dissipates excess voltage as heat, so verify your input-to-output differential and load current against thermal limits, and consider a switching regulator where efficiency matters. This is another heavily counterfeited commodity part: require lot and date-code traceability. State quantity, packing and traceability requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ADP151AUJZ-3.3-R7 is an Analog Devices ultralow-noise CMOS low-dropout linear regulator with a fixed output — the output voltage is written into the order code itself — in the 5-lead TSOT package family, on tape and reel, per the ADP151 datasheet Rev. J. It is the precision member of its class on this site: features and ratings, including the dropout figure at its stated load current and the ripple-rejection figure at its stated frequency, are given with their datasheet conditions in the parameter table — use those, not the higher dropout figure that circulates in secondary copy. The AUJZ package mapping, reel quantity and marking code are verified in the parameter table. Parameters verified against the ADI datasheet Rev. J. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

LTC4359IMS8#PBF is an Analog Devices ideal-diode controller in MSOP-8, tube — for redundant power supplies and automotive battery protection: OR-ing two rails without the voltage drop and heat of Schottky diodes. 4 V to 80 V operation driving a single N-channel MOSFET is the selection point: near-zero forward drop with fast reverse turn-off when a source fails. Selection advice: the #PBF suffix denotes the lead-free version; this is the controller only — the external MOSFET sets the current rating, so size it for your load. Smooth switchover without oscillation suits telecom and server holdup. −40 °C to +85 °C. ADI lists this part as Active through distribution. Parameters verified against distributor and manufacturer documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.
