300mA HIGH SPEED, EXTREMELY LOW NOISE CMOS LDO REGULATOR

AP2125

General Description

The AP2125 series are 300mA, positive voltage regu-

lator ICs fabricated by CMOS process.

Each of these ICs is equipped with a voltage reference,

an error amplifier, a resistor network for setting output

voltage, a chip enable circuit, a current limit circuit and

OTSD (over temperature shut down) circuit to prevent

the IC from over current and over temperature.

The AP2125 series have features of high ripple rejec-

tion, low dropout voltage, low noise, high output volt-

age accuracy and low current consumption which

make them ideal for use in various battery-powered

apparatus.

The AP2125 have 1.8V, 2.5V, 2.8V, 3.0V, 3.3V, 4.15V

and 4.2V fixed voltage versions.

These ICs are available in tiny SC-70-5 and SC-82

packages as well as industry standard SOT-23-3 and

SOT-23-5 packages.

Features

Excellent Ripple Rejection: 70dB Typical (1.8V
