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.
