The RT9080 is a low-dropout (LDO) voltage regulator featuring an enable function ,operating over a wide input voltage range from 1.2V to 5.5V. The RT9080 delivers a maximum output current of 600mA and is designed for low-power operation, all within a compact package.
The features of low quiescent current, as low as 2μA, and almost zero disable current, are ideal for powering battery equipment for a longer service life. The RT9080 is stable with the ceramic output capacitor over its wide input range from 1.2V to 5.5V and the entire range of output load current (0mA to 600mA).
