The TPS746115PQWDRBRQ1 is a 1-A 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 TPS746-Q1 has low quiescent current consumption and provides fast line and load transient performance.

The TPS746115PQWDRBRQ1 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 TPS746115PQWDRBRQ1 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.
