L7805CV from UMW, 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	IN	power_in	Unregulated positive input voltage. For 5 V output devices, VI must be at least ~7 V and not exceed 35 V (absolute max). A 0.33 µF ceramic bypass capacitor to GND is recommended close to the pin.
2	GND	power_in	Common ground reference for the input and output. The tab of the TO-220 package is electrically connected to this pin and serves as the thermal/heat-sink path.
3	OUT	power_out	Regulated +5 V output, typically 5 V (4.8-5.2 V at TJ=25 °C) with up to 1.2 A load capability. A 0.1 µF ceramic capacitor to GND at the pin is recommended for stability and transient response.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`l7805cv.step`	83 KB	You want the bare part, or you mark your own boards.
`l7805cv-etched.step`	686 KB	You want the part with `L7805CV` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 180 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.
