说明

The TPS779xx is a low-dropout regulator with integrated power-on reset. The device is capable of supplying 250 mA of output current with a dropout of 200 mV (TPS77930). Quiescent current is 92 uA at full load dropping down to 1 uA when the device is disabled. The device is optimized to be stable with a wide range of output capacitors including low ESR ceramic (10uF) or low capacitance (1uF) tantalum capacitors. The device has extremely low noise output performance (55 uV_rms) without using any added filter capacitors. TPS779xx is designed to have a fast transient response for larger load current changes.

The TPS779xx is offered in 1.8-V, 2.5-V, and 3-V fixed-voltage versions and in an adjustable version (programmable over the range of 1.
