High Accuracy Adjustable Shunt Regulator

TL431(D)

第 1 页共 6 页

GENERAL DESCRIPTION

The TL431 is a three-terminal adjustable

regulator series with a guaranteed thermal

stability over applicable temperature ranges. The

output voltage may be set to any value between

Vref (approximately 2.495 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 -40℃ to +125℃.

FEATURES
