Product Summary

The TL431BVDR2G integrated circuit is a three-terminal programmable shunt regulator diode. The monolithic IC voltage reference operates as a low temperature coefficient zener which is programmable from Vref to 36 V with two external resistors. The TL431BVDR2G exhibits a wide operating current range of 1.0 mA to 100 mA with a typical dynamic impedance of 0.22 Ω. The characteristics of the reference 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 the TL431BVDR2G convenient to obtain a stable reference from 5.0 V logic supplies, and since the device operates as a shunt regulator, it can be used as either a positive or negative voltage reference.
