L7805CDT from UMW, in a TO-252. 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	I	power_in	Unregulated input voltage. Accepts 7 V to 25 V (35 V absolute max) for the 5 V output part; a 0.33 µF ceramic bypass capacitor to GND is recommended close to the pin.
2	G	power_in	Common ground reference for both the input and the output. On the TO-252 (DPAK) package the tab is electrically connected to this pin.
3	O	power_out	Regulated +5 V output (4.8 V-5.2 V typ. at TJ=25 °C), up to 1.2 A. A 0.1 µF ceramic capacitor to GND close to the pin is recommended for stability.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`l7805cdt.step`	119 KB	You want the bare part, or you mark your own boards.
`l7805cdt-etched.step`	1.4 MB	You want the part with `L7805CDT` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 373 faces against 83 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.
