2A CMOS LDO REGULATOR
AP2132B
General Description
Features
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
VOUT reaches 92% of its rating value. And it operates
with VIN as low as 1.4V and VCTRL voltage 5V with
output voltage programmable as low as 0.8V.
Adjustable Output: 0.8V to 3.0V
Low Dropout Voltage: [email protected] IOUT=2A,
VOUT=1.2V
Over Current and Over Temperature Protection
Enable Pin
PSOP-8 Package with Thermal Pad
Maximum Output Current: 2A
High Output Voltage Accuracy: 2%
VOUT Power Good Signal
Excellent Line/Load Regulation
Applications
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.
