DATA SHEET .onsemi. Programmable Precision References NCP431A, SC431A, NCP431B, SC431B, NCP432B, SC432B Series 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...
