PROGRAMMABLE VOLTAGE REFERENCE
ADJUSTABLE OUTPUT VOLTAGE : 2.5 to 36V� SINK CURRENT CAPABILITY : 1 to 100mA� TYPICAL OUTPUT IMPEDANCE : 0.22Ω 1% AND 2% VOLTAGE PRECISION
DESCRIPTIONThe 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 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.

1) ΔVref is defined as the difference between the maximum and minimum values obtained over the full temperature range.
ΔVref = Vref max. - Vref min. Pd is calculated with Tamb = +25°C, Tj = +150°C and Rthja = 200°C/W for TO92 package = 130°C/W for SO8 batwing package
