SC431BVSNT1G

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 A to 100 mA
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 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.
