The TPS74525PQWDRVRQ1 is a 500-mA ultra-low dropout regulator (LDO) with power good. The device is available in a small 6-pin 2mm × 2mm WSON package with wettable flanks and a small 8-pin 3mm × 3mm VSON package for easy optical inspection. The TPS745-Q1 has low quiescent current consumption and provides fast line and load transient performance.

The TPS74525PQWDRVRQ1 supports an input voltage range of 1.5V to 6.0V and an externally adjustable output voltage range of 0.55V to 5.5V, making it a flexible post-regulator device. The device also provides a fixed output voltage to power common voltage rails.

The TPS74525PQWDRVRQ1 has a power good (PG) output that monitors the voltage at the feedback pin to indicate the output voltage status. The EN input and PG output can be used to sequence multiple power supplies in the system.

The TPS74525PQWDRVRQ1 is stable when paired with small ceramic output capacitors enabling a small overall solution size. The precision bandgap and error amplifier features high accuracy, offering ±0.85% (max) accuracy at 25°C and ±1.5% (max) accuracy over the full operating temperature range. The device includes integrated thermal shutdown, current limit, and undervoltage lockout (UVLO) functions. The TPS745-Q1 has an internal foldback current limit to help reduce heat dissipation during short-circuit events.
