TPS767D301PWPR

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.

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. Ranked #6 on the lcsc.com flash-sale page (2026-10-16). Parameters verified against Texas Instruments documentation.

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.

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. 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.

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.

F: 3.0-A standalone switch-mode buck charger with NVDC power path for single-cell Li-Ion/Li-polymer, 3.9-13.5-V input, 19.5-mohm BATFET, 9.5-uA battery leakage, WQFN-24. A: Full FET integration and hardware-configurable JEITA profile deliver fast charging without host firmware management. B: Shorter firmware development and faster time-to-market for portable devices. E: Ranked on hqbuy.com real-time hot list (2026-10-14). Selection advice: pick BQ25616 over the I2C siblings BQ25618/BQ25619 when the host MCU should not own charging registers; note this RTWR orderable is the WQFN-24 tape-and-reel option.

BQ25790 is Texas Instruments’ 5-A buck-boost battery charger for 1-to-4-cell Li-ion/Li-polymer packs in 2.9x3.3mm WCSP-56 — for USB-C PD charging where input voltage swings both above and below the battery voltage: the integrated buck-boost stage (all four switching FETs plus battery FET on-chip) automatically transitions between buck, boost and buck-boost without host intervention. 97% charging efficiency at 30 W, 3.6-to-24 V input range, NVDC power-path management that keeps the system alive even with a dead or removed battery, dual-input selector (USB, barrel, wireless, solar), D+/D- handshake for legacy fast-charge adapters, and I2C host control with an integrated ADC for telemetry. USB-C/PD compatible, -40 to +85°C. Selection advice: the WCSP package is the smallest footprint option — for easier assembly specify the QFN sibling BQ25792; for solar-input designs the BQ25798 variant adds MPPT. State cell count and input source mix in the RFQ so the offered lot is matched to the right charge profile. Parameters verified against Texas Instruments documentation.
