The RT9073A is a low-dropout (LDO) voltage regulators with enable function that operates from 1.2V to 5.5V. It provides up to 250mA of output current and offers low-power operation in miniaturized packaging. The features of low quiescent current as low as 1μA and almost zero disable current is ideal for powering the battery equipment to a longer service life. The RT9073A 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 250mA).
