CJ7805 3% from Jiangsu, in a TO-252-2(DPAK). 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, 7 V to 25 V typical (35 V absolute max). Bypass with a 0.33 μF ceramic capacitor to GND placed close to the pin for stability.
2	GND	power_in	Common ground reference for input and output. On TO-252-2L this pin is also the tab (die attach paddle), providing the primary thermal path to the PCB copper.
3	OUT	power_out	Regulated +5 V output (4.75-5.25 V over temperature) with up to 1.5 A peak current. Bypass with a 0.1 μF ceramic capacitor to GND close to the pin to improve transient response.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cj7805-3.step`	119 KB	You want the bare part, or you mark your own boards.
`cj7805-3-etched.step`	2.0 MB	You want the part with `CJ7805 3%` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 484 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.
