The TPS771xx and TPS772xx are low-dropout
250
regulators with integrated power-on reset and
VDO – Dropout Voltage – mV
power good (PG) function respectively. These
200
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
150
IO = 150 mA
dropping down to 1 µA when device is disabled.
