The NCP431/NCP432 integrated circuits are three−terminal

programmable shunt regulator diodes. These monolithic IC voltage

references operate as a low temperature coefficient zener which is

programmable from Vref to 36 V using two external resistors. These

devices exhibit a wide operating current range of 40 mA to 100 mA

with a typical dynamic impedance of 0.22 W. 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 V reference makes it convenient to obtain a

stable reference from 5.0 V logic supplies, and since the NCP431/

NCP432 operates as a shunt regulator, it can be used as either a

positive or negative voltage reference. Low minimum operating

current makes this device an ideal choice for secondary regulators in

SMPS adapters with extremely low no−load consumption.
