CC6209ST from Cross chip, in a TSOT-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	VIN	power_in	Unregulated input supply voltage. Bypass to GND with a ceramic capacitor placed close to the pin.
2	GND	power_in	Ground reference for the regulator.
3	EN	input	Enable input. Drive high to enable the regulator, low to place the device into low-current shutdown.
4	NC	unconnected	No internal connection. May be left floating or tied to GND.
5	VOUT	power_out	Regulated output voltage. Requires an output ceramic capacitor for stability.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cc6209st.step`	59 KB	You want the bare part, or you mark your own boards.
`cc6209st-etched.step`	1.8 MB	You want the part with `CC6209ST` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 421 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.
