TL431XA3

Description

The TL431 series are three-terminal adjustable regulators with guaranteed

TO-92

thermal stability over applicable temperature ranges. The output voltage

may be set to any value between VREF (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

• 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
