L7805ABV 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	VI	power_in	Unregulated DC input voltage. Must be at least ~2 V above the nominal 5 V output (dropout) and no more than 35 V absolute maximum. A 0.33 µF bypass capacitor to GND close to the pin is recommended.
2	GND	power_in	Common ground reference for both input and output. On the TO-220FP the tab is electrically isolated from this pin (fully-plastic package), so the tab does not carry the ground potential.
3	VO	power_out	Regulated +5 V output, up to 1.5 A with adequate heat sinking. A 0.1 µF output capacitor to GND is recommended for transient response; internal current-limiting, thermal-shutdown and SOA protection make the output essentially indestructible.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`l7805abv.step`	83 KB	You want the bare part, or you mark your own boards.
`l7805abv-etched.step`	756 KB	You want the part with `L7805ABV` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 200 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.
