Description

The TL431 is a programmable shunt voltage

reference with guaranteed temperature stability

over the entire temperature range of operation.

The output voltage may be set to any value

between 2.5V and 36V with two external resistors.

The TL431 operates with a wide current range

from

1

to

100mA

with

a

typical

dynamic

impedance of 0.22

Ω.
