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 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.
