TL431CN Datasheet PDF - STMicroelectronics

DESCRIPTION
The TL431 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 TL431operates with a wide current range from 1 to 100mA with a typical dynamic impedance of 0.22Ω.
