LM285MX-1.2 from Texas Instruments, in a SOIC-8. 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 | NC | unconnected | No internal connection; not connected to the die per the SOIC connection diagram. |
| 2 | NC | unconnected | No internal connection; not connected to the die per the SOIC connection diagram. |
| 3 | NC | unconnected | No internal connection; not connected to the die per the SOIC connection diagram. |
| 4 | - | passive | Negative (anode) terminal of the 2-terminal band-gap voltage reference diode, the low side of the reverse-breakdown voltage measured to pin 8. |
| 5 | NC | unconnected | No internal connection; not connected to the die per the SOIC connection diagram. |
| 6 | NC | unconnected | No internal connection; not connected to the die per the SOIC connection diagram. |
| 7 | NC | unconnected | No internal connection; not connected to the die per the SOIC connection diagram. |
| 8 | + | passive | Positive (cathode) terminal of the 2-terminal band-gap voltage reference diode; operated in reverse breakdown over 10μA to 20mA with a nominal 1.235V (1.223V-1.247V) drop to pin 4. |
