XB385M3-2.5

XINLUDA · Voltage Reference · SOT-23-3

XB385M3-2.5 from XINLUDA, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 + passive Positive (cathode) terminal of the shunt voltage reference. Develops the 2.5 V reference voltage relative to pin 2 when biased with a reverse current between 20 µA and 20 mA.
2 - passive Negative (anode) terminal of the shunt voltage reference. Typically tied to circuit ground / return.
3 NC/DAP unconnected No electrical function. Internally attached to the Die Attach Pad (DAP); should be connected to pin 2 (anode) or left floating per the datasheet note.
