NCP431ACLPRAG

onsemi · Voltage References · TO-92-3

NCP431ACLPRAG from onsemi, in a TO-92-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Reference input Reference input of the internal 2.5 V reference, with a continuous reference input current range of −5 to +10 mA.
2 Anode passive Anode terminal of the programmable shunt regulator, with cathode-to-anode voltage rated up to 37 V maximum.
3 Cathode passive Cathode terminal of the shunt regulator, with continuous cathode current range of −100 to +150 mA and recommended operation from Vref up to 36 V.
