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-

external resistors.

The TL1431 operates with a wide current range

from 1 to 100mA with a typical dynamic impedance

of 0.2

Ω.
