description
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 when device is disabled. These devices are optimized to be stable with a wide range of output capacitors including low ESR cer...
