TECHNICAL DATA
PROGRAMMABLE PRECISION REFERENCES
The KIA431S/AS/BS 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 20 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
KIA431S/AS/BS operates as a shunt regulator, it can be used
as either a positive or negative voltage reference.
