The AP2132A is a positive voltage regulator IC fabricated by CMOS process. The IC 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 AP2132A has features of large current, low-dropout voltage, high output-voltage accuracy and low input voltage. The AP2132A provides 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.
The AP2132A is available in 1.8V fixed output voltage version and adjustable output voltage version. The fixed version integrates 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 is available in the PSOP-8 package.
