SEMICONDUCTOR
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.
