DATA SHEET www.onsemi.com 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.
