DESCRIPTION
The TL1431 is a programmable shunt voltage ref-
erence with guaranteed temperature stability over
the entire temperature range of operation.
The output voltage may be set to any value be-
tween V_ref (approximately 2.5V) and 36V with two
external resistors.
The TL1431 operates with a wide current range
from 1 to 100mAwith a typical dynamic impedance
of 0.2Ω.
