产品详细说明

TPS74501PQWDRVRQ1 is an adjustable 500 mA automotive LDO from Texas Instruments, packaged as a six-pin wettable-flank WSON for compact point-of-load regulation.

The 1.5 to 6 V input range and 0.55 to 5.5 V adjustable output let a designer derive a lower rail from an existing board supply rather than dedicate a separate converter to each low-current load.

Its power-good output reports when the feedback voltage is in range, so a downstream device or second rail can be enabled only after this supply has settled.

A 1 µF minimum output capacitor keeps the regulator circuit small, while the specified 45 dB rejection at 100 kHz helps isolate sensitive loads from switching ripple upstream.

The DRV package has wettable flanks for optical solder inspection, a useful assembly distinction on automotive boards qualified across the AEC-Q100 Grade 1 ambient range.
