LM2931AZ-5.0G from onsemi, in a TO-92. 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 | Output | power_out | Regulated output; the datasheet states output currents in excess of 100 mA with an input-to-output differential of less than 0.6 V at 100 mA. |
| 2 | GND | power_in | Ground reference pin; the datasheet gives no specific voltage or current limit for this pin. |
| 3 | Input | power_in | Unregulated input; the datasheet gives a continuous maximum of 40 Vdc, transient input of 60 Vpk for 100 ms or less, and transient reverse polarity of -50 Vpk. |
