TL431 Programmable Precision Reference

he TL431 integrated circuits are three-terminal programmable shunt regulator diodes.

T_{These monolithic IC voltage references operate as a low temperature coefficient zener}

which is programmable from Vref to 36 volts with two external resistors. This device exhibits a

wide operating current range of 1.0 to 100 mA 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 2.5 volt

reference makes it convenient to obtain a stable reference from 5.0 volt logic supplies, and

since the TL431 operates as a shunt regulator, it can be used as either a positive or negative

voltage reference
