KIA431BF Datasheet 3-terminal programmable shunt regulator diodes

Manufacturer: KEC

Overview: 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.
