TL431A Datasheet | onsemi

DATA SHEET .onsemi. Programmable Precision References TL431A, B Series, NCV431A, B Series, SCV431A The TL431A, B integrated circuits are three- terminal programmable shunt regulator diodes. These monolithic IC voltage references operate as a low temperature coefficient zener which is 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...
