JSM6206A3.0MR from JSMSEMI, 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	VSS	power_in	Chip ground (0V reference). Common return for input and output. Should be connected to the system single-point ground.
2	VOUT	power_out	Regulated 3.0V output (±2.5%). Sources up to 250mA when Vin=4.3V; supports up to 500mA absolute max. Requires ≥1µF (typ. 10µF) ceramic output capacitor for stability.
3	VIN	power_in	Regulator input (labeled '启动输入端'/enable-input in the datasheet). Recommended operating range ~3.3V-6.5V for 3.0V output; absolute max 6.5V. Requires ≥1µF (typ. 10µF) input ceramic capacitor.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`jsm6206a3-0mr.step`	59 KB	You want the bare part, or you mark your own boards.
`jsm6206a3-0mr-etched.step`	2.5 MB	You want the part with `JSM6206A3.0MR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 595 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.
