Description
General part information
TPS745-Q1 Series
The TPS745 is an adjustable 500-mA low-dropout (LDO) regulator with power-good functionality. This device is available in a small, 6-pin, 2-mm × 2-mm WSON package and consumes very low quiescent current and provides fast line and load transient performance. The TPS745 features an ultra-low dropout of 130 mV at 500 mA that can help improve the power efficiency of the system.
The TPS745 is optimized for a wide variety of applications 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 low output voltage enables this LDO to power the modern microcontrollers with lower core voltages.
The TPS745 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 the sequencing multiple power sources in the system.
