XT385-2.5

XINLUDA · Voltage Reference · TO-92-3

XT385-2.5 from XINLUDA, in a TO-92-3. 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 - passive Anode (negative) terminal of the 2.5V micropower band-gap reference diode, drawn in the TO-92 bottom view connected to the diode triangle side.
2 + passive Cathode (positive) terminal of the 2.5V reference diode, which operates over 20 uA to 20 mA reverse current.
3 NC unconnected Pin 3 is shown in the TO-92 bottom view with no connection to the diode symbol.
