AP432AYG-13 is a three-terminal adjustable low-dropout voltage regulator for which current can be drawn up to 200 milliamps. It is used in personal computers, mobile phones, video games and other consumer electronics products. Its main function is to provide a reference voltage with an accuracy of ±10%.

This voltage reference regulator is an integrated circuit containing a bandgap reference core, an error amplifier, an adjustable resistor circuit and an output stage. The internal bandgap reference core is able to maintain an accurate voltage reference with minimum temperature drift and output impedance.

The error amplifier is used to set the output voltage. It compares the output voltage with a resistor-divider feedback voltage to adjust the controlling voltage across the output pass transistors. The adjusting resistor allows for adjustable control of the output voltage which can be regulated down to 1.3V.

The output stage consists of two pass transistors which regulate the voltage at the output terminal. These transistors are powered by the controlling voltage from the error amplifier and are distributed so that the current provided by the AP432AYG-13 can be drawn from either output terminal.

The AP432AYG-13 is a precision, high-performance voltage reference regulator. It has a wide operating voltage range from 1.3V to 20V and a low quiescent current thus making it ideal for low power applications. The improved accuracy of ±10% ensures that output voltages are within a small tolerance band. The stability of the voltage reference regulator is also ensured by the high immunity to temperature variations and the low output impedance, making it suitable for medium to high performance applications.

In summary, AP432AYG-13 is a precision, high-performance voltage reference three-terminal adjustable low-dropout voltage regulator. It has a wide input voltage range from 1.3V to 20V and adjustable output voltage with an accuracy of ±10%.The output current capability is up to 200 milliamps, and the output is constant over a wide range of temperature and output impedance. It is suitable for use in personal computers, mobile phones, video games and other consumer electronics products.
