XC6210B332MR from TECH PUBLIC, in a SOT-23-5. 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	VIN	power_in	Unregulated input supply. Operating range 2.0V to 6.0V (absolute max VSS-0.3 to VSS+7V). Bypass to GND with a 1uF ceramic capacitor close to the pin.
2	GND	power_in	Device ground / VSS reference. Connect to system ground; also the return for CIN and COUT bypass capacitors.
3	CE	input	Chip Enable (active high). VCE >= 0.6V enables the regulator; VCE <= 0.3V shuts it down (ISHDN typ 0.1uA). Do not leave floating.
4	NC	unconnected	No internal connection. Leave open or tie to GND.
5	OUT	power_out	Regulated 3.3V output (±2%), up to 800mA continuous. Requires a 1uF ceramic output capacitor for stability.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`xc6210b332mr.step`	85 KB	You want the bare part, or you mark your own boards.
`xc6210b332mr-etched.step`	2.6 MB	You want the part with `XC6210B332MR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 618 faces against 102 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.
