Supply, recycling automotive (TI) TPS74550PQWDRVRQ1 500mA, ultra-low voltage drop regulator (LDO).


summarize

The TPS74550PQWDRVRQ1 is a 500mA ultra-low voltage drop regulator (LDO) with normal power supply indication. The device is available in a small 6-pin 2mm × 2mm WSON package with wettable sides for easy optical inspection. The TPS745-Q1 has low static current consumption and provides fast line and load transient performance.


The TPS745-Q1 has a power Normal (PG) output that monitors the feedback pin voltage to indicate the output voltage status. The EN input and PG output can be used to sequence multiple power supplies in the system.
