Supply TI Chip TPS74525PQWDRVRQ1 Low Dropout Voltage Regulator

Product Description
TPS74525PQWDRVRQ1 is a 500-mA ultra-low-dropout regulator (LDO) with power-good functionality. TPS74525PQWDRVRQ1 consumes low quiescent current and provides fast line and load transient performance.
TPS74525PQWDRVRQ1 is a flexible device for post-regulation by supporting an input voltage range from 1.5 V to 6.0 V and an externally adjustable output range of 0.55 V to 5.5 V. The device also features fixed output voltages for powering common voltage rails.
TPS74525PQWDRVRQ1 has a power-good (PG) output that monitors the voltage at the feedback pin to indicate the status of the output voltage. The EN input and PG output can be used for sequencing multiple power supplies in the system.
