PROGRAMMABLE VOLTAGE REFERENCE
s ADJUSTABLE OUTPUT VOLTAGE :
2.5 to 36V
s SINK CURRENT CAPABILITY : 1 to 100mA s TYPICAL OUTPUT IMPEDANCE : 0.22 s 1% AND 2% VOLTAGE PRECISION
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 2.5V and 36V with two external resistors. The TL431 operates with a wide current range from 1 to 100mA with a typical dynamic impedance of 0.22.
