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. |
