AS431BKTR-E1

Overview

The AS431BKTR-E1 is a three-terminal adjustable precision shunt regulator manufactured by Diodes Incorporated. It provides programmable output voltage from 2.5V to 36V with 1.0% initial accuracy and a typical temperature coefficient of 20PPM/°C. The device operates within a cathode current range of 1mA to 100mA and supports an operating ambient temperature range of -40°C to +125°C. Packaged in SOT25, it features low output impedance and sharp turn-on characteristics.

Feature Summary

Programmable precise output voltage ranging from 2.5V to 36V
High stability under capacitive load conditions
Low equivalent full-range temperature deviation
Sink current capacity spanning 1mA to 100mA

Applications

Switching power supply regulation
Charger circuits
