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. |
