BL8071GCLATR33 from BL Shanghai Belling, in a SOT-223. 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	VDD	power_in	Supply voltage input. Operating range 1.5V to 6V (absolute max 6V). Bypass with a 4.7uF input capacitor to GND close to the pin.
2	GND	power_in	Ground / device return. Also serves as the primary thermal path through the SOT-223 tab.
3	VOUT	power_out	Regulated output voltage. For the -33 order code the output is fixed at 3.3V ±2%, capable of sourcing up to 1.5A. Decouple with a 4.7uF output capacitor to GND.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`bl8071gclatr33.step`	64 KB	You want the bare part, or you mark your own boards.
`bl8071gclatr33-etched.step`	2.6 MB	You want the part with `BL8071GCLATR33` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 621 faces against 75 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.
