DESCRIPTION
The TL431 is a programmable shunt voltage refer-
ence with guaranteed temperature stability over
the entire temperature range of operation.
The output voltage may be set to any value be-
tween Vref (approximately 2.5V) and 36V with two
external resistors.
The TL431 operates with a wide current range from
1 to 100mA with a typical dynamic impedance of
0.22Ω.
