LD1117S12CTR

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.

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.

TLV1117-33IDCYR is a Texas Instruments 3.3 V fixed 800 mA LDO regulator in SOT-223 — for 3.3 V rails: 4.7–15 V input, 1.2 V dropout at 800 mA, -40°C to +125°C, over-current and thermal shutdown. Selection advice: the -33IDCYR code is the fixed 3.3 V SOT-223 on reel — for adjustable output use the TLV1117IDCYR; the DCY package needs copper pour for the 800 mA rating. Parameters verified against Texas Instruments documentation. State quantity, packing and date-code 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 3.3 V LDO regulator in TSOT-23-5, tape and reel — for noise-sensitive rails: RF, VCO and PLL supplies where output noise matters more than current. 9 microvolt RMS noise with no bypass capacitor required is the selection point: ultralow noise without the extra capacitor that competing LDOs need. Selection advice: the R7 suffix denotes tape and reel on a 7-inch reel; against the LD1086DT33TR on this site — the ADP151 is the 200 mA precision part, the LD1086 the 1.5 A workhorse. 2.2 V to 5.5 V input, 150 mV dropout at 200 mA, 70 dB PSRR at 10 kHz. −40 °C to +125 °C. ADI lists this part as Active through distribution. Parameters verified against distributor and manufacturer documentation.

MCP1700-3302E/TO is a Microchip 3.3 V 250 mA CMOS LDO in TO-92-3 — for battery and IoT: 1.6 µA typical quiescent current, 2.3–6 V input, -40°C to +125°C. The ultra-low quiescent current is the selection point: years of standby on coin cells where a standard LDO would drain the battery. Selection advice: the /TO code is the TO-92 through-hole — for SMT use the SOT-23 or SOT-89 variants; the 250 mA rating suits sensor nodes, not power-hungry radios. Parameters verified against Microchip documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TPS70933DBVR is a Texas Instruments 3.3V fixed low-dropout linear regulator in a 5-pin SOT-23 package - for always-on 3.3V rails: 150mA output, 2.7V to 30V input, 1.4uA typical quiescent current, plus-minus 2 percent output accuracy, 960mV typical dropout at 150mA, 80dB typical PSRR, enable pin, reverse-current protection, thermal shutdown, overcurrent protection and undervoltage lockout, -40C to 125C junction range. The ultra-low quiescent current with 30V input tolerance is the selection point: a 3.3V rail that survives wide industrial inputs while drawing almost nothing in standby, which stretches battery life in always-on nodes. Business impact: one tiny LDO covers wide-input 3.3V regulation from 24V industrial buses down to low-voltage rails, so one qualified code serves multiple power trees. Selection advice: the DBVR code is the SOT-23-5 3000-piece tape-and-reel packing - for other fixed outputs pick the matching TPS709xx code; keep input above 3.3V plus dropout at full load, and use the reverse-current protection for rails that may be back-fed by a battery or a second supply.

TPS767D301PWPR is a Texas Instruments dual 1A low-dropout linear regulator -- for multi-rail embedded power: 10V maximum input, one fixed 3.3V output plus one adjustable 1.5V to 5.5V output, 85uA quiescent current, enable and reset/power-good outputs, over-current, thermal and reverse-polarity protection, 28-pin HTSSOP, -40C to +125C. Two independent 1A rails in one package cut the regulator count on dense boards, and the 85uA Iq keeps standby budgets low for always-on domains. Business impact: consolidating two rails into a single qualified part simplifies the BOM and the approval paperwork -- one datasheet, one reliability file, one sourcing line. Selection advice: the PWPR suffix is the HTSSOP-28 reel -- verify the exposed thermal pad is soldered to a copper pour, since dual 1A dissipation at high dropout needs the thermal path; for single-rail needs, a single-output LDO costs less per rail.

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.

LD1117S33TR is an STMicroelectronics 3.3 V fixed low-drop positive voltage regulator in SOT-223, tape-and-reel packing (TR) — up to 800 mA output current, 1.1 V dropout at 800 mA, ±1% output tolerance at 25 °C (±2% over the full temperature range), 75 dB typical supply-voltage rejection, internal current and thermal limiting, up to 15 V input, 0 to +125 °C. The NPN pass transistor is the selection point: quiescent current flows mostly into the load, so efficiency stays reasonable at light load, and only a 10 µF output capacitor is needed for stability — the classic, no-surprises 3.3 V rail for MCU boards, peripherals and legacy 5 V to 3.3 V drops. Selection advice: the S33 is the 3.3 V fixed member and TR is tape and reel — the adjustable LD1117S-TR uses a 1.25 V reference with two resistors for custom rails; budget the 1.1 V dropout plus SOT-223 thermal limits at 800 mA, and add copper area or a larger package for continuous full-load current. ST lists LD1117S33TR as Active. Evidence: ST LD1117 datasheet and distributor listings confirm 3.3 V, 800 mA, 1.1 V dropout, ±1%, SOT-223 and tape-and-reel packing. Match the full LD1117S33TR code.

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 in one package, simple to drive, nearly indestructible. 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.
