These devices are capable of supplying 150 m A of output current with a dropout of 115 m V (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 ceramic (10 µF) or low capacitance (1 µF) tantalum capacitors. These devices have extremely low noise output performance (55 µVrms) without using any added filter capacitors. TPS771xx and TPS772xx are designed to have fast transient response for larger load current changes. 200 150 100 50 0 -...
