TPS77128-Q1 150-mA LDO REGULATORS

The TPS771xx and TPS772xx are low-dropout regulators with integrated power-on reset and power good (PG) function respectively. These devices are capable of supplying 150 mA of output current with a dropout of 115 mV (TPS77133, TPS77233). Quiescent current is 92 µA at full load dropping down to 1 µA .

TPS77128-Q1 Features

* a sleep mode; applying a TTL high signal to EN (enable) shuts down the regulator, reducing the quiescent current to less than 1 µA at TJ = 25°C. The TPS771xx features an integrated power-on reset, commonly used as a supply voltage supervisor (SVS) or reset output voltage. The RESET output of the TPS
