2.495V Programmable Shunt Voltage Reference

GENERAL DESCRIPTION

TS431

series

integrated

circuits

are

three-terminal

programmable shunt regulator diodes. These monolithic

IC voltage references operate as a low temperature

coefficient zener which is programmable from VREF to 36

volts with two external resistors. These devices exhibit a

wide operating current range of 1.0 to 100mA with a

typical dynamic impedance of 0.22Ω.

The characteristics of these references make them

excellent

replacements

for

zener

diodes

in

many

applications such as digital voltmeters, power supplies,

and op amp circuitry. The 2.5V reference makes it

convenient to obtain a stable reference from 5.0V logic

supplies, and since The TS431 series operates as a

shunt regulator, it can be used as either a positive or

negative stage reference.
