AP432ARL-7

Overview

The AP432ARL-7 is a three-terminal adjustable precision shunt regulator manufactured by Diodes Incorporated. It features a reference voltage of 1.24V with ±1% tolerance and supports an output voltage range from 1.24V to 20V via external resistors. The device provides a sink current capability of 200mA, requires a minimum cathode current of 150μA for regulation, and exhibits a dynamic output impedance of 0.2Ω. It operates within a temperature range of -20°C to +85°C and utilizes the SC59R surface-mount package.

Feature Summary

Provides precise programmable output voltage using two external resistors
Features fast turn-on response characteristics suitable for Zener diode replacement
Ensures stable operation across extended commercial temperature ranges
Offers low dynamic output impedance and low output noise

Applications

Voltage monitoring circuits
Over-voltage and under-voltage protection systems
Constant-current sinks and sources
Crowbar circuits
