AP7333-33SAG-7 from Diodes Incorporated, 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	IN	power_in	Voltage input pin, 2V to 6V (7V absolute max). Bypass to GND with at least a 1µF capacitor placed close to the pin.
2	OUT	power_out	Regulated 3.3V output pin, up to 300mA continuous. Requires a 1µF ceramic capacitor to GND for stability; dropout is ~300mV at 300mA.
3	GND	power_in	Device ground reference. Connect directly to the system ground plane; return path for input and output bypass capacitors.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ap7333-33sag-7.step`	59 KB	You want the bare part, or you mark your own boards.
`ap7333-33sag-7-etched.step`	2.5 MB	You want the part with `AP7333-33SAG-7` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 605 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.
