TPS70933DBVR

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.

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.

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.

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.

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.

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.

LD1117S12CTR is an STMicroelectronics fixed 1.2V low-dropout linear regulator in SOT-223 - for 1.2V core rails feeding FPGAs, DSPs, MCUs and ASICs from higher-voltage buses. Up to 800mA output current with a typical 1V dropout, plus or minus 1 percent output tolerance at 25C and 75dB typical supply rejection is the selection point: a tight, quiet 1.2V rail from a jelly-bean part that needs only a 10uF minimum output capacitor for stability. The business case is rail simplicity and noise: the NPN pass transistor keeps quiescent current flowing mostly into the load, and on-chip current and thermal limiting protect both the regulator and the downstream core during faults. Evidence: ST lists LD1117S12CTR as Active in its official store with an official datasheet, and the SOT-223 surface-mount package offers solid thermal performance for its size. Selection advice: the S12 code fixes the 1.2V output - do not confuse it with the 1.8V, 2.5V, 3.3V or 5V fixed versions, or with the adjustable LD1117; the CTR suffix denotes SOT-223 on tape and reel; size the copper pour for the dissipation at your actual input-to-output differential, since at 800mA a large drop turns into real heat in SOT-223. Heat basis: Ranked #6 on hqbuy.com real-time hot list (2026-10-15). Parameters verified against STMicroelectronics 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.

The LP5907QMFX-3.3Q1 is an AEC-Q100 Grade 1 automotive LDO that delivers a fixed 3.3 V rail at up to 250 mA from a 2.2 V to 5.5 V input. Its 6.5 uVRMS output noise and 82 dB PSRR at 1 kHz make it a clean supply for noise-sensitive RF, sensor and ADC circuits, while 12 uA quiescent current (under 1 uA when disabled) stretches battery life in always-on automotive modules. A 120 mV typical dropout keeps the rail alive through low-battery dips, and +/-2 percent output tolerance with thermal and short-circuit protection reduces field failures and warranty cost. The device is stable with small 1 uF ceramic capacitors, needs no noise bypass capacitor, and supports remote output capacitor placement, which shrinks layout effort and BOM count. Selection advice: this MFX ordering code is the fixed 3.3 V SOT-23-5 option; if your design needs a different rail, choose another fixed-voltage LP5907-Q1 code from the same family, and do not parallel devices because the datasheet specifies a single 250 mA channel.

TLV62568DBVR is a Texas Instruments 1 A synchronous step-down buck converter in SOT-23-5 (DBV), tape-and-reel packing (R) — 2.5 V to 5.5 V input, adjustable output from 0.6 V up to VIN, up to 95% efficiency, 35 µA operating quiescent current, 1.5 MHz typical switching frequency, power-save mode for light-load efficiency, 100% duty cycle for lowest dropout, internal soft start, overcurrent and thermal-shutdown protection, −40 to +125 °C. The adjustable output with 100% duty cycle is the selection point: one part generates 1.2 V, 1.8 V, 3.3 V or any logic rail from a 5 V or Li-ion source with near-zero dropout, so the same footprint covers multiple rails across a board — a general-purpose point-of-load workhorse for set-top boxes, cameras, routers and disk drives. Selection advice: the DBV is the 5-pin SOT-23; the R suffix is tape and reel. The adjustable TLV62568 covers what the fixed-output members of the family do plus any custom rail — confirm the exact fixed-output code only if the BOM specifies one. TI lists TLV62568DBVR as Active. Evidence: TI TLV62568 datasheet (SLVSD89) and distributor listings confirm 1 A, 2.5–5.5 V, 0.6 V to VIN, SOT-23-5 and tape-and-reel packing. Match the full TLV62568DBVR code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.
