CJ6206A33M from Changjing, in a SOT-23-3L. 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	VSS	power_in	Ground return for the regulator. Common reference for VIN and VOUT.
2	VOUT	power_out	Regulated output pin. Provides the fixed 3.3 V output (accuracy ±2% typ.), up to 300 mA. Requires a low-ESR ceramic output capacitor (1 µF typical).
3	VIN	power_in	Unregulated supply input, 2.0 V to 7.0 V operating range (absolute max VSS-0.3 V to VSS+8 V). Bypass with a 1 µF low-ESR ceramic capacitor to VSS.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cj6206a33m.step`	59 KB	You want the bare part, or you mark your own boards.
`cj6206a33m-etched.step`	2.2 MB	You want the part with `CJ6206A33M` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 509 faces against 69 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.
