TPS77925 采用 MSOP8 封装的 250mA 低压降 (LDO) 稳压器和 SVS,启用高电平

TPS77925 描述

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 uVrms) 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
