XL336-2.5

XINLUDA · Voltage Reference · SOP-8

XL336-2.5 from XINLUDA, in a SOP-8. 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 NC unconnected No internal connection. Leave floating or optionally tie to ground.
2 NC unconnected No internal connection.
3 NC unconnected No internal connection.
4 - passive Cathode / negative terminal of the shunt reference (the '−' pin in the connection diagram). Return leg of the 2.5V shunt; typically tied to ground when the reference is used in the conventional two-terminal configuration.
5 ADJ input Adjust terminal. Allows trimming of the 2.5V breakdown voltage (±120 mV typical trim range with a 10 kΩ pot per Figure 1) and, with two series signal diodes, minimization of the temperature coefficient. If unused, may be left floating.
6 NC unconnected No internal connection.
7 NC unconnected No internal connection.
8 + passive Anode / positive terminal of the shunt reference (the '+' pin in the connection diagram). Biased through a series resistor from the supply so that 400 µA ≤ IR ≤ 10 mA; the 2.5V reference appears across the +/− terminals.
