NCP432BVSNT1G

onsemi · Voltage Reference · SOT-23-3

NCP432BVSNT1G from onsemi, in a SOT-23-3. 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 Cathode passive Cathode of the shunt regulator, rated for a cathode-to-anode voltage up to 37 V and a continuous cathode current of −100 to +150 mA (0.04 to 100 mA recommended).
2 Reference input Reference input that sets the programmable output voltage (Vref, 2.5 V typical), with a continuous reference input current range of −5 to +10 mA.
3 Anode passive Anode of the shunt regulator, serving as the reference terminal for the cathode-to-anode voltage rating of 37 V maximum.
