TL431 three-terminal programmable shunt regulator diode

Order this document by TL431/D TL431, A, B Programmable Precision References The TL431, A, 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 Ω. The characteristics of these references make them .
