TL1431 PROGRAMMABLE VOLTAGE REFERENCE . . . . ADJUSTABLE OUTPUT VOLTAGE : Vref to 36V SINK CURRENT CAPABILITY : 1 to 100mA TYPICAL OUTPUT IMPEDANCE : 0.2 0.4% AND 0.25% VOLTAGE PRECISION Z TO92 (Plastic Package) D SO8 (Batwing Plastic Micropackage) DESCRIPTION The TL1431 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 resistors. The TL1431 operates with a wide current range from 1 to 100mAwith a typical dynamic impedance of 0.2.
