TPS7B6925QDCYRQ1

TPS7B6933QDCYRQ1 is a Texas Instruments TPS7B6933-Q1 automotive 150 mA LDO with fixed 3.3 V output in SOT-223-4, tape and reel — AEC-Q100 qualified, 4 V to 40 V input (45 V transient withstand), 15 microamp typical quiescent current, short-circuit and overcurrent protection with UVLO, −40 °C to +105 °C ambient. The SOT-223 package is the selection point: the same AEC-Q100 3.3 V die as the SOT-23-5 QDBVRQ1, but with a tab for real thermal headroom — when the 3.3 V logic rail runs near full current from a high input voltage, the SOT-223 sheds the heat the SOT-23 cannot. Selection advice: pick the QDCYR when dropout times current pushes dissipation past what a SOT-23 handles; pick the QDBVRQ1 when the rail current is light and board area matters. Same 15 microamp always-on Iq, same fixed 3.3 V, same automotive qualification either way. Evidence: TI TPS7B69xx datasheet confirms SOT-223-4, AEC-Q100, 4–40 V and 150 mA. Match the full TPS7B6933QDCYRQ1 code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TPS7B6950QDCYRQ1 is a Texas Instruments TPS7B6950-Q1 automotive 150 mA LDO with fixed 5 V output in SOT-223-4, tape and reel — AEC-Q100 qualified, 4 V to 40 V input (45 V transient withstand), 15 microamp typical quiescent current, short-circuit and overcurrent protection with UVLO, −40 °C to +105 °C ambient. The 5 V fixed output is the selection point: the standard automotive 5 V sensor and legacy-logic rail — with AEC-Q100 qualification and always-on 15 microamp Iq in a thermally capable SOT-223. Selection advice: pick the 5 V code for 5 V sensors and legacy peripherals; the 2.5 V TPS7B6925 and 3.3 V TPS7B6933 codes are footprint-compatible for the other rails. The SOT-223 tab handles the higher dissipation of a 5 V rail fed from automotive 12/24 V better than the SOT-23-5 QDBVRQ1. The 40 V input with 45 V transient withstand rides through load dump without a pre-regulator. Evidence: TI TPS7B69xx datasheet confirms SOT-223-4, AEC-Q100, fixed 5 V, 4–40 V and 150 mA. Match the full TPS7B6950QDCYRQ1 code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TPS7B6925QDBVRQ1 is a Texas Instruments TPS7B6925-Q1 automotive 150 mA LDO with fixed 2.5 V output in SOT-23-5, tape and reel — AEC-Q100 qualified, 4 V to 40 V input (45 V transient withstand), 15 microamp typical quiescent current, short-circuit and overcurrent protection with UVLO, −40 °C to +105 °C ambient. The Q1 automotive qualification is the selection point: this is the always-on rail part for body electronics, clusters and standby MCUs that must survive load-dump transients and sip current when the vehicle sleeps. Selection advice: the 15 microamp Iq is the headline — for always-on 2.5 V sensor and MCU rails, it beats generic LDOs by an order of magnitude on standby drain. The fixed 2.5 V needs no divider; for 3.3 V use the TPS7B6933QDBVRQ1, for 5 V the TPS7B6950QDBVRQ1. The SOT-23-5 suits low-current rails; for better thermal headroom use the SOT-223 TPS7B6925QDCYRQ1. Evidence: TI TPS7B69xx datasheet confirms AEC-Q100, 4–40 V, 150 mA, 15 microamp Iq and SOT-23-5. Match the full TPS7B6925QDBVRQ1 code.

TPS7B6933QDBVRQ1 is a Texas Instruments TPS7B6933-Q1 automotive 150 mA LDO with fixed 3.3 V output in SOT-23-5, tape and reel — AEC-Q100 qualified, 4 V to 40 V input (45 V transient withstand), 15 microamp typical quiescent current, short-circuit and overcurrent protection with UVLO, −40 °C to +105 °C ambient. The 3.3 V fixed output is the selection point: the standard automotive logic rail — CAN transceivers, MCUs and sensors — with AEC-Q100 qualification and always-on 15 microamp Iq in a SOT-23-5. Selection advice: against the 2.5 V TPS7B6925QDBVRQ1, this is the pick for 3.3 V logic; against the 5 V TPS7B6950QDBVRQ1, pick by rail voltage — the three parts are footprint-identical, so one layout serves all three rails. For higher dissipation use the SOT-223 TPS7B6933QDCYRQ1. The 40 V input with 45 V transient withstand rides through automotive load dump without a pre-regulator. Evidence: TI TPS7B69xx datasheet confirms AEC-Q100, fixed 3.3 V, 4–40 V, 150 mA and SOT-23-5. Match the full TPS7B6933QDBVRQ1 code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

LM317DCY is a Texas Instruments LM317 adjustable positive linear regulator — 1.25 to 37 V output set by two external resistors, 1.5 A maximum, in the 4-pin SOT-223 surface-mount package (DCY), tube packing of 80, operating 0 to +125 °C. Internal current limiting, thermal overload protection and safe-area compensation are the selection point: the classic regulator that survives abuse fixed-output parts cannot. Selection advice: the SOT-223 package is the binding constraint, not the 1.5 A headline — at high input-output differentials the package thermal resistance forces real-world current well below 1.5 A, so compute dissipation for your rails or step up to the TO-220 (KCS) variant for heatsinking. This is a standard bipolar regulator with about 2 V dropout, not a low-dropout part: on a 5 V rail it cannot reliably deliver 3.3 V at load and temperature, where an LD1086-class LDO can. The DCY (no R) code is tube packing for prototyping and small runs — for SMT production lines order LM317DCYR, the 2500-reel version, and do not mix packing codes on one BOM line. Evidence: TI LM317 datasheet and package addendum confirm 1.25-37 V, 1.5 A, SOT-223 DCY, tube 80.

LM317DCYR is a Texas Instruments LM317 adjustable positive linear regulator — 1.25 to 37 V output set by two external resistors, 1.5 A maximum, in the 4-pin SOT-223 surface-mount package (DCY), tape-and-reel packing of 2500, operating 0 to +125 °C. It is the same die as the tube-packed LM317DCY; the R suffix is the selection point for procurement: reel packing for automated SMT lines and volume builds, with a 2500-piece reel that sets the practical MOQ. Selection advice: choose this code when the board goes to pick-and-place — tube parts slow the line — and keep LM317DCY on prototype and rework BOMs only. Electrically the same cautions apply as the tube version: internal current limit, thermal and safe-area protection, but about 2 V of dropout, so it is not a low-dropout regulator and cannot make 3.3 V from a 5 V rail at full load the way an LD1086 can; and the SOT-223 thermal path caps real continuous current well below the 1.5 A headline at large input-output differentials. Evidence: TI LM317 datasheet and package addendum confirm 1.25-37 V, 1.5 A, SOT-223 DCY, reel 2500.

BQ4050RSMR is a Texas Instruments battery fuel gauge — for 1-series Li-ion and Li-polymer packs: Impedance Track gauging algorithm for accurate state-of-charge reporting, integrated protection-friendly architecture, VQFN-12 package. The Impedance Track algorithm learns the cell characteristics over cycles, so reported capacity stays accurate as the battery ages — unlike simple coulomb counters that drift; accurate gauging prevents both unexpected shutdowns and over-conservative capacity margins. Business impact: reliable fuel gauging is a safety and user-experience feature — medical, industrial and consumer devices all depend on trustworthy remaining-capacity readings. Selection advice: the RSMR code denotes VQFN-12 on tape and reel — the BQ4050 targets single-cell packs — for multi-cell designs look at the BQ40 family stackable gauges; cell characterization data improves initial accuracy. Ranked #15 on the hqbuy.com real-time hot list (2026-10-05). Parameters verified against Texas Instruments documentation.
