PROGRAMMABLE PRECISION REFERENCES

The KIA431AA/BA/CA Series integrated circuits are three-terminal

programmable shunt regulator diodes.

These monolithic IC voltage reference operate as a low temperature

external resistors. It features a low mnimum cathode current for regulation.

The typical value of 50uA make the parts ideal for low power application.

These devices exhibit a wide operating current range of 0.1mA to 100mA

with a typical dynamic impedance of 0.22

Ω.

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 KIA431AA/BA/CA Series

operates as a shunt regulator, it can be used as either a positive or negative

voltage reference.

FEATURES

・Programmable output voltage to 36V

・Low Minimum Operation Current : 50μA(Typ.@25℃)

・Low Dynamic Output Impedance : 0.22Ω(Typ.).

・Sink Current Capability of 0.1mA to 100mA.

・Typical Temperature Drift : 5mV (0℃ to 70℃)
