HE6206-33NR from HEERMICR, 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	VSS	power_in	Ground / negative supply reference (0 V). Connect directly to the system ground plane.
2	VOUT	power_out	Regulated 3.3V output (VOUT x 0.98 to VOUT x 1.02, ±2% tolerance). Supplies up to 300 mA (limited by Pd of the SOT-23 package, ~0.20 W). Requires a ceramic output capacitor (1.0 µF typical) for stability.
3	VIN	power_in	Unregulated input supply. Absolute max 8 V; must be at least VOUT + Vdrop (typ. 0.19 V, max 0.35 V at Iout=100mA for VOUT=3.3V). Bypass with a 1.0 µF ceramic input capacitor.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`he6206-33nr.step`	59 KB	You want the bare part, or you mark your own boards.
`he6206-33nr-etched.step`	2.1 MB	You want the part with `HE6206-33NR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 511 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.
