Low Power, 14V, 200mA LDO Regulator


Update Alert Share

The RT9077 is a low-dropout (LDO) voltage regulator with enable function offering benefits of up to 14V input voltage, low-dropout, low-power operation, and miniaturized packaging.

The features of low quiescent current and almost zero disable current is ideal for powering the battery equipment to a longer service life. The RT9077 is stable with ceramic output capacitors over its wide input range from 3.5V to 14V and entire range of output load current (0mA to 200mA).
