TL431 Overview

Precision low voltage reference

Features

Product Name: Precision Low Voltage Reference

Product model: TL431

Product Description:

The TL431 is a three-terminal adjustable regulator series with a guaraneed thermal stability

over applicable temperature ranges. The output voltage may be set to any value between

Vref (approximately 2.5 volts) and 40 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.

The TL431 is characterized for operation from -0℃ to +70℃.

parameter:

Cathode Voltage VKA 40 V

Continuous Cathode Current Range IK -100 ~ 150 mA

Reference Input Current Range IREF 0.05 ~ 10 mA

Power Dissipatin at 25℃:
