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 excel

® TL431 PROGRAMMABLE VOLTAGE REFERENCE . . . . ADJUSTABLE OUTPUT VOLTAGE : 2.5 to 36V SINK CURRENT CAPABILITY : 1 to 100mA TYPICAL OUTPUT IMPEDANCE : 0.22Ω 1% AND 2% VOLTAGE PRECISION Z TO92 (Plastic Package) N DIP8 (Plastic Package) DESCRIPTION The TL431 is a programmable shunt voltage reference with guaranteed temperature stability over the entire temperature range of operation. The output voltage may be set to any value between Vref (approximately 2.5V) and 36V with two external resis
