AP2125
300mA, HIGH SPEED, EXTREMELY LOW NOISE CMOS LDO REGULATOR
Description
Pin Assignments
The AP2125 series are 300mA, positive voltage regulator 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 rejection, low dropout
voltage, low noise, high output voltage 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 packages as well as industry
standard SOT-23-3 and SOT-23-5 packages.
