LM285MX-2.5 from Texas Instruments, in a SOIC-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; not connected to the die. |
| 2 | NC | unconnected | No internal connection; not connected to the die. |
| 3 | NC | unconnected | No internal connection; not connected to the die. |
| 4 | - | power_in | Cathode/negative reference terminal (ground side) of the 2-terminal band-gap reference diode. |
| 5 | NC | unconnected | No internal connection; not connected to the die. |
| 6 | NC | unconnected | No internal connection; not connected to the die. |
| 7 | NC | unconnected | No internal connection; not connected to the die. |
| 8 | + | power_in | Anode/positive reference terminal; reverse breakdown (VREF) is developed across this pin and Pin 4 when operated in the 20 µA to 20 mA reverse current range. |
