SGM2034-3.0YN3G from SGMICRO, in a SOT-23-3. 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 pin. Common return for the regulator input and output.
2	OUT	power_out	Regulated output pin (3.0V nominal, ±1.2% accuracy at +25°C, up to 250mA). Requires a ceramic output capacitor of 0.1μF to 10μF placed as close as possible to the pin.
3	IN	power_in	Input supply voltage pin (1.7V to 7.5V operating; absolute max 8V). Requires a 1μF or larger ceramic capacitor from IN to GND placed as close as possible to the pin.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sgm2034-3-0yn3g.step`	59 KB	You want the bare part, or you mark your own boards.
`sgm2034-3-0yn3g-etched.step`	2.7 MB	You want the part with `SGM2034-3.0YN3G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 640 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.
