The TPR431 and TPR432 are adjustable shunt voltage references with guaranteed temperature stability over the operating temperature range. The device temperature range is extended from −40 °C up to +125 °C. The output voltage can be set to any value between 2.5 and 36 V with two external resistors. The TPR431 operates with a wide current range from 1 to 80 mA with a typical dynamic impedance of 0.2 Ω.
