CYStek Product Specification

Adjustable Precision Shunt Regulators

TL431XN3

Description

The TL431XN3 series are three-terminal adjustable regulators with guaranteed thermal stability over

2.495 volts) and 36 volts with two external resistors. These devices have a typical dynamic output

impedance of 0.2

Ω. 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

• Temperature coefficient is 50ppm/°C typical

• Temperature compensated for operation over full temperature range

• Low output noise voltage

• Fast turn on response

• Pb-free package
