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 from1 to 100mAwith a typical dynamic impedance of 0.2Ω.
