L7805CD2T from UMW, in a TO-263. 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 DC input. Recommended 7 V to 25 V for 5 V output; absolute maximum 35 V. A 0.33 µF ceramic input decoupling capacitor to GND is recommended close to the pin to ensure stability.
2	GND	power_in	Common ground for both input and output. On TO-252 (DPAK) this pin is electrically connected to the exposed thermal tab, which should be soldered to a copper heatsink pad to dissipate power (RthJC = 8 °C/W, RthJA = 100 °C/W for TO-252).
3	OUT	power_out	Regulated +5 V output (4.8 V-5.2 V typ. at TJ=25 °C, IO=500 mA). Sources up to 1.2 A subject to thermal and SOA limits. A 0.1 µF ceramic output capacitor to GND is recommended for transient response and stability.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`l7805cd2t.step`	108 KB	You want the bare part, or you mark your own boards.
`l7805cd2t-etched.step`	1.6 MB	You want the part with `L7805CD2T` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 418 faces against 79 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.
