2A CMOS LDO REGULATOR AP2132B

Data Sheet

General Description

The AP2132B series are positive voltage regulator
ICs fabricated by CMOS process. The ICs consist of
a voltage reference, an error amplifier, a power
transistor, a resistor network for setting output
voltage, a current limit circuit for current protection,
and a chip enable circuit.

The AP2132B series have features of large current,
low dropout voltage, high output voltage accuracy,
low input voltage. The AP2132B provides a power
good (PG) signal to indicate if the voltage level of
V

reaches 92% of its rating value. And it operates

OUT

with V
output voltage programmable as low as 0.8V.

The AP2132B are available in 1.2V, 1.5V, 1.8V, 2.5V
fixed output voltage versions and adjustable output
voltage version. The fixed versions integrate the
adjust resistors. It is also available in an adjustable
version, which can set the output voltage with
external resistor. If the pin of adjustable output
voltage is to ground, it will switch to fixed output
voltage.

AP2132B series are available in PSOP-8 package.
