Programmable Precision References NCP431A, SC431A, NCP431B, SC431B, NCP432B, SC432B Series The NCP431/NCP432 integrated circuits are three−terminal Pin 1. Reference programmable shunt regulator diodes. These monolithic IC voltage 2. Anode 1 1 references operate as a low temperature coefficient zener which is 2 2 3 3. Cathode 3 programmable from Vref to 36 V using two external resistors. These STRAIGHT LEAD BENT LEAD devices exhibit a wide operating current range of 40 mA to 100 mA BULK PACK TAPE & REEL AMMO PACK 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
