References  
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.
