SSP6206-33NR from Shanghai Siproin Microelectronics, in a SOT-23. 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	GND	power_in	Ground / Vss reference pin. Common return for input, output, and internal reference. Labeled Vss in the typical application schematic.
2	VOUT	power_out	Regulated output pin. Delivers fixed 3.3 V (-33 option) up to 300 mA. Requires a ~1.0 µF ceramic output capacitor (CL) to ground for stability.
3	VIN	power_in	Unregulated input supply pin, 1.6 V to 8 V (abs max 8 V). Requires a ~1.0 µF ceramic input capacitor (CIN) to ground. Dropout typically 0.19 V at 100 mA for Vout ≥ 2.8 V.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ssp6206-33nr.step`	59 KB	You want the bare part, or you mark your own boards.
`ssp6206-33nr-etched.step`	2.6 MB	You want the part with `SSP6206-33NR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 603 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.
