TECHNICAL DATA
KIA431 Series
BIPOLAR LINEAR INTEGRATED CIRCUIT
PROGRAMMABLE PRECISION REFERENCES
The KIA431 Series 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 36 volts with two external resistors. These devices exhibit a wide operating current range of 1.0 to 100mA 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. The 2.5 volt
reference makes it convenient to obtain a stable reference from 5.0 volt logic supplies, and since the KIA431 Series
operates as a shunt regulator, it can be used as either a positive or negative voltage reference.

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 = 8.0mV and slope is positive,
Vref at 25 =2.495V, Ta=70
0.008 106
Vref = 70
= 45.8 ppm/
(2.495)
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 )
Vref Max.
Vref Min.
Vref = Vref (Max.)
- Vref (Min.)
Ta = T2 - T1
T1 T2
AMBIENT TEMPERATURE
The average temperature coefficient of the Reference
input voltage, Vref , is defined as:

Vref (

= Vref 106
Ta(Vref at 25 )
Vref can be positive or negative depending on whether
Vref Min. or Vref Max. occurs at the lower ambient temperature.
