LM285M-1.2

HGSEMI LM285M 1 2 TR · Voltage Reference · SOP-8

LM285M-1.2 from HGSEMI LM285M 1 2 TR, 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
4 ANODE passive Anode of the shunt voltage reference (positive current inflow terminal is CATHODE; ANODE is the return leg, typically tied to ground). Combined with CATHODE it establishes the 1.235 V reference across the device.
8 CATHODE passive Cathode of the shunt voltage reference. Driven from a supply through a bias resistor at 100 µA-20 mA; clamps to ~1.235 V (LM285-1.2, ±55 mV tolerance ungraded, ±12 mV for B-grade) relative to ANODE.
1 NC unconnected No internal connection. Leave floating or tie to a convenient net; not electrically connected to the die.
2 NC unconnected No internal connection. Leave floating or tie to a convenient net; not electrically connected to the die.
3 NC unconnected No internal connection. Leave floating or tie to a convenient net; not electrically connected to the die.
5 NC unconnected No internal connection. Leave floating or tie to a convenient net; not electrically connected to the die.
6 NC unconnected No internal connection. Leave floating or tie to a convenient net; not electrically connected to the die.
7 NC unconnected No internal connection. Leave floating or tie to a convenient net; not electrically connected to the die.
