TECHNICAL DATA
KIA431AA/BA/CA Series
BIPOLAR LINEAR INTEGRATED CIRCUIT
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
coefficient zener which is programmable from V_ref to 36 volts with two
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 0.22ʃ.
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.
