BCD AP2132AMP-1.8TRG1 Peak 3a cmos ldo regulator with enable and power good Datasheet

Data Sheet
Peak 3A CMOS LDO Regulator with Enable and Power Good
General Description
Features
The AP2132A 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 AP2132A have features of large current, low
dropout voltage, high output voltage accuracy and
low input voltage. The AP2132A provide a power
good (PG) signal to indicate if the voltage level of
VOUT reaches 92% of its rating value. And it operates
with a VIN as low as 1.4V and VCTRL voltage 5V with
output voltage programmable as low as 0.6V.
AP2132A
Adjustable Output: 0.6V to 3.0V
Low Dropout Voltage: 300mV at IOUT=2A,
VOUT=1.2V
Over Current and Over Temperature Protection
Enable Pin
PSOP-8 Package with Thermal Pad
Maximum Output Current: 3A (Peak)
High Output Voltage Accuracy: 2%
VOUT Power Good Signal
Excellent Line/Load Regulation
Applications
The AP2132A 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.
