CJ7806 from Changjing, 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. Operating range must be at least Vo + dropout (~2V at 1A) up to 35V absolute maximum. A 0.33 uF ceramic bypass capacitor to GND is recommended close to the pin for stability.
2	GND	power_in	Common ground reference for input and output. On TO-252-2L the GND lead is fused to the tab (heat slug), providing the primary thermal path (RθJA = 80 °C/W).
3	OUT	power_out	Regulated +6V output (5.75 V to 6.25 V at 25 °C). Sources up to 1.5A peak with internal current-limit around 550 mA short-circuit and 2.2A peak protection. A 0.1 uF output bypass capacitor to GND is recommended for transient response.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cj7806.step`	119 KB	You want the bare part, or you mark your own boards.
`cj7806-etched.step`	1.5 MB	You want the part with `CJ7806` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 378 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.
