Product Brief
2A CMOS LDO Regulator
Description
The AP2132 are positive Voltage regulator ICs
fabricated by CMOS process. It consists 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 AP2132 have features of large current, low
dropout voltage, high output voltage accuracy, low
input voltage, The AP2132 provides a Power Good
(PG) signal to indicate if the voltage level of V
OUT
reaches 92% of its rating value. And it operates
with a
V
IN
as low as 1.4V and V
PP
voltage 5V with
output voltage programmable as low as 0.6V.
The AP2132 is available in 1.2V, 1.5V, 1.8V, 2.5V
fixed output voltage versions and ADJ 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.
