NH6302A33M from NH, 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	Ground / network return terminal. All voltages are referenced to this pin.
2	VOUT	power_out	Regulated 3.3V output. Delivers up to 300mA. Requires a 1µF output capacitor (ceramic or tantalum) from VOUT to VSS close to the pin for loop stability.
3	VIN	power_in	Unregulated supply input, 2.5V to 18V operating (absolute max 24V). A 1µF input capacitor is recommended; when driven from a live source through an MLCC, add a ~3Ω series resistor to suppress start-up transients.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`nh6302a33m.step`	59 KB	You want the bare part, or you mark your own boards.
`nh6302a33m-etched.step`	2.1 MB	You want the part with `NH6302A33M` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 495 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.
