ST TL431 TL432 handbook
The TL431 and TL432 are programmable shunt voltage references with guaranteed temperature stability over the entire operating temperature range. 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.
