General Description

The AP2132 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 AP2132 have features of large current, low

dropout voltage, high output voltage accuracy, and

low input voltage. The AP2132 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 VPP voltage 5V with output

voltage programmable as low as 0.6V.

The AP2132 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 AP2132 series are available in PSOP-8 package.
