TL431A Voltage Reference Shunt Regulator integrated circuits are three-terminal programmable shunt regulator diodes. These monolithic IC voltage references operate as a low-temperature coefficient Zener programmable from Vref to 36 V with two external resistors.
These devices exhibit a wide operating current range of 1.0 mA to 100 mA with a typical dynamic impedance of 0.22 W. 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 V reference makes it convenient to obtain a stable reference from 5.0 V logic supplies. Since the TL431, A, B operates as a shunt regulator, it can be used as a positive or negative voltage reference.
