RT9080
2μA I_Q, 600mA Low-Dropout Linear Regulator
General Description
Features
The RT9080 is a low-dropout (LDO) voltage regulators with
enable function that operates from 1.2V to 5.5V. It provides
up to 600mA of output current and offers low-power
operation in miniaturized packaging.
The features of low quiescent current as low as 2μA 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 1.2V to 5.5V and the entire range of output load
current (0mA to 600mA).
