TECHNICAL DATA
PROGRAMMABLE PRECISION REFERENCES
The KIA2431P/S/T/AP/AS/AT/BP/BS/BT are integrated
circuits are three-terminal programmable shunt regulator diodes.
These monolithic IC voltage reference operate as a low temperature
coefficient zener which is programmable from Vref to 16 volts with
two external resistors.
These devices exhibit a wide operating current range of 80 A
to 50mA with a typical dynamic impedance of 0.22 .
The characteristics of these references make them excellent
replacements for zener diodes in many applications such as
digital voltmeters, power supplies, and op amp circuitry.
FEATURES

Note 1:
The deviation parameter Vref is defined as the differences
between the maximum and minimum values obtained over the
full operating ambient temperature range that applies.
Example : Vref = 5.0mV and slope is positive,
Vref at 25 =1.245V, Ta=110
0.005 106
Vref = 110
= 36.5 ppm/
1.245
Note 2: The dynamic impedance Zka is defined as:
VKA
|Zka| = Ik
When the device is programmed with two external
resistors, R1 and R2, (refer to Figure 2) the total
dynamic impedance of the circuit is defined as:
R1
|Zka’| = |Zka| (1+ R2 )
