Description
General part information
TPS746-Q1 Series
The TPS746-Q1 is a 1-A, ultra-low-dropout regulator (LDO) with power-good functionality. This device is available in a small 6-pin, 2-mm × 2-mm WSON package and a small 8-pin, 3-mm × 3-mm VSON package with wettable flanks to facilitate optical inspection. The TPS746-Q1 consumes low quiescent current and provides fast line and load transient performance.
The TPS746-Q1 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.
The TPS746-Q1 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.
