TL431CLPRPG

onsemi · Voltage Reference · TO-92-2.54mm

TL431CLPRPG from onsemi, in a TO-92-2.54mm. 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 passive Reference input of the TL431 that sets the output via the external divider, with a continuous reference input current range of −0.05 to +10 mA.
2 Anode passive Anode terminal of the shunt regulator, with cathode-to-anode voltage rated at 37 V maximum (recommended Vref to 36 V).
3 Cathode passive Cathode terminal of the shunt regulator, recommended to operate at 1.0 mA to 100 mA with a continuous absolute range of −100 to +150 mA.
