Adjustable Precision Shunt Regulators

TL431A3

Description

TO-92

The TL431A3 series are three-terminal adjustable regulators with

guaranteed thermal stability over applicable temperature ranges. The output voltage may be set to any

value between V^REF(approximately 2.495 volts) and 36 volts with two external resistors. These devices

have a typical dynamic output impedance of 0.2Ω. Active output circuitry provides a very sharp turn-on

characteristic, making these devices excellent replacement for zener diodes in many applications.

Features

• Programmable output voltage

• Low output noise voltage

• Fast turn on response

• Pb-free package

• Temperature coefficient is 50ppm/°C typical

• Temperature compensated for operation over

• full temperature range
