Description

The TL431 and TL432 are adjustable shunt

voltage references with guaranteed temperature

stability over the entire operating temperature

range. The device temperature range is extended

for the automotive version 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 TL431 and TL432 operate with a

wide current range from 1 to 100 mA with a typical

dynamic impedance of 0.22 Ω.
