L7805CV-DG from STMicroelectronics, in a TO-220. 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 | INPUT | power_in | Unregulated DC input supply (V_I). Accepts up to 35 V absolute maximum for the 5 V output variant. A 0.33 µF ceramic capacitor to GND close to the pin is recommended for stability and to filter input noise. |
| 2 | GROUND | power_in | Common ground reference for the regulator. Connected to the TO-220 mounting tab. Carries the quiescent current plus any load return current back to the input supply's negative rail. |
| 3 | OUTPUT | power_out | Regulated +5 V DC output (V_O). Delivers up to 1.5 A with adequate heatsinking; internally current-limited and thermally protected. A 0.1 µF ceramic capacitor to GND near the pin improves transient response. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 226 faces against 48 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
