RT9078中文资料2μA IQ, 300mA 低压差线性稳压器数据手册Richtek规格书

描述 Description

The RT9078 is a low-dropout (LDO) voltage regulator with an enable function that operates from a 1.2V to 5.5V supply. It provides up to 300mA of output current in miniaturized packaging.

The device features a 2μA low quiescent current and 0.5μA shutdown current, making it ideal for battery-powered applications requiring extended service life. Additional features include a current limit function, over-temperature protection, and output discharge function.

The recommended junction temperature range is -40°C to 125°C.
