TPS74501PQWDRVRQ1

TPS74501PQWDRVRQ1 is the automotive-grade adjustable member of the TI TPS745 LDO family, supplied in a 2x2 mm WSON-6 (DRV) package. It accepts a 1.5 V to 6.0 V input and delivers up to 500 mA, with the output set by a feedback divider anywhere from 0.55 V to 5.5 V, so one qualified code can serve several point-of-load rails across a vehicle platform. Output accuracy is +/-0.85% maximum at 25 C and +/-1.5% maximum over temperature, which keeps rail margins tight for ADCs, sensors and RF front ends. An open-drain power-good flag, UVLO, current limit and thermal shutdown simplify rail supervision and fault handling, and AEC-Q100 Grade 1 qualification covers -40 C to +125 C operation. Selection advice: the 01 code is the adjustable version - for a fixed rail, choose the matching fixed-output TPS745 code instead of redesigning the divider; the WDRV code fixes this 2x2 mm WSON, while the DRB sibling is a 3x3 mm VSON-8 with wettable flanks for optical inspection. Do not confuse this code with TPS74501PBQWDRVRQ1, a different ordering variant. Parameters verified against Texas Instruments documentation.
