XB431-TL

XINLUDA · Voltage References · SOT-23

XB431-TL from XINLUDA, in a SOT-23. 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 Ref input REF input pin whose threshold is related to the voltage of the anode pin, which sets the programmed output voltage (2.5 V to 36 V range).
2 Cathode bidirectional Cathode is the voltage input and shunts the regulated current; recommended cathode voltage is up to 36 V and cathode current 1 mA to 100 mA.
3 Anode output Anode must be connected directly to GND, per the datasheet pin function table.
