NCV1117DTARKG from onsemi, in a DPAK. 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	ADJ/GND	input	Adjust pin (adjustable version) or Ground (fixed-voltage versions). On adjustable devices, this pin sinks ~52 uA (120 uA max) and sets Vout via an external resistor divider referenced to the 1.25 V Vref. On fixed devices, this pin is the device ground return.
2	VOUT	power_out	Regulated positive output. Delivers up to 1.0 A continuous with typical current limit of 1.5 A (2.2 A max). Requires a 10 uF output capacitor for stability. The DPAK heatsink tab is internally connected to this pin.
3	VIN	power_in	Unregulated positive input supply, maximum 20 V. Requires a 10 uF input capacitor. Dropout voltage is typically 1.07 V at 800 mA and 1.2 V max over temperature.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ncv1117dtarkg.step`	119 KB	You want the bare part, or you mark your own boards.
`ncv1117dtarkg-etched.step`	1.6 MB	You want the part with `NCV1117DTARKG` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 450 faces against 83 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.
