AZ1117H-3.3TRG1 from Diodes, in a SOT-223. 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	GND	power_in	Ground reference for the fixed-output (3.3V) regulator. On adjustable versions this pin is the ADJ feedback pin, but on fixed-voltage variants (e.g. AZ1117H-3.3) this pin is connected internally as GND.
2	OUTPUT	power_out	Regulated 3.3V output (typ 3.3V, tolerance approx +/-1% at 10mA). Supplies up to 1A continuous. A minimum 22uF (tantalum recommended) output capacitor is required for stability.
3	INPUT	power_in	Unregulated input supply, absolute max 20V, recommended operating max 15V. Must exceed VOUT by the dropout voltage (typ 1.15V at 1A). A 10uF input capacitor is recommended.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`az1117h-3-3trg1.step`	64 KB	You want the bare part, or you mark your own boards.
`az1117h-3-3trg1-etched.step`	2.0 MB	You want the part with `AZ1117H-3.3TRG1` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 520 faces against 75 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.
