Description

The TL431 three-terminal shunt reference combines

low temperature co-efficient zener band-gap regulation

with programmability. The device operates over a

wide 1mA to 100mA current range with voltage

resistors. With high temperature stability and typical

dynamic impedance of 0.27Ω, these references make

excellent replacements for zener diodes in many high

provides a stable reference from 5V logic supplies.

The device is simple to implement, highly reliable and

can be used as either positive or negative reference.
