LM385BD-2.5R2G from onsemi, 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. Leave floating or tie to a convenient node. |
| 2 | NC | unconnected | No internal connection. |
| 3 | NC | unconnected | No internal connection. |
| 4 | Anode | passive | Anode of the reference diode. Typically returned to the circuit ground/return. The device regulates V(BR)R = 2.500 V (min 2.462 / max 2.538 V at 25 °C) from Cathode to Anode when biased with 20 µA to 20 mA of reverse current. |
| 5 | NC | unconnected | No internal connection. |
| 6 | NC | unconnected | No internal connection. |
| 7 | NC | unconnected | No internal connection. |
| 8 | Cathode | passive | Cathode of the reference diode. Positive terminal when the device is reverse-biased. Held at ~2.500 V above the Anode over the operating current range (IRmin ≈ 13 µA typ, up to 20 mA). |
