Richtek introduces low quiescent low-dropout linear regulator, the RT9080. To squeeze more energy out of a small battery, using products with low quiescent current (Iq) is the best choice. Richtek recognizes the growing demand for portable and wearable devices.
The RT9080 is a low-dropout (LDO) voltage regulator with enable function that operates from 1.2 V to 5.5 V. It provides up to 600 mA of output current and offers low-power operation in miniaturized packaging.
The features of low quiescent current as low as 2 μA and almost zero disable current is ideal for powering the battery equipment to a longer service life. The RT9080 is stable with the ceramic output capacitor over its wide input range from 1.2 V to 5.5 V and the entire range of output load current (0 mA to 600 mA).
