Brief overview of the content in a NCP431A PDF file

NCP431A SC431A NCP431B NCP432B Series Programmable Precision 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 Features http onsemi com 12 TO 92 LP SUFFIX CASE 29 11 Pin 1 Reference 2 Anode 3 Cathode 3 8 1 Cathode Anode Anode NC Top View 1 SOIC 8 NB D SUFFIX CASE 751 Reference Anode Anode NC Programmable Output Voltage to 36 V Low Minimum Operating Current 40 mA Typ 2
