LM285M3-1.2

HGSEMI · Voltage Reference · SOT-23

LM285M3-1.2 from HGSEMI, in a SOT-23. 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 CATHODE passive Cathode (阴极) of the shunt voltage reference. Tied to the positive side; regulates to 1.235 V (typ) above the anode when biased with 100 μA-20 mA of reverse current.
2 ANODE passive Anode (阳极) of the shunt voltage reference. Typically tied to circuit ground / return; the 1.235 V reference is developed from cathode to anode.
3 NC unconnected No internal connection. Leave floating or tie to any convenient node; not electrically connected to the die.
