Peak 3A CMOS LDO Regulator with Enable and Power Good AP2132A

Data Sheet

General Description

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 V

reaches 92% of its rating value. And it operates

OUT

with a V output voltage programmable as low as 0.6V.

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.

The AP2132A series are available in PSOP-8 package.
