μμμμμA I

Q, 250mA Low-Dropout Linear Regulator

Applications



Portable, Battery Powered Equipment



Ultra Low Power Microcontrollers



Notebook computers

General Description

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 1

μA 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).
