L7815CD2T-TR from STMicroelectronics, in a D2PAK. 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	INPUT	power_in	Unregulated positive supply input (Vi). Absolute maximum 35 V for the 15 V version; typical operating range ≈17 V to 30 V. Recommend a 0.33 µF bypass capacitor from INPUT to GND close to the device.
2	GROUND	power_in	Common ground / return pin. Electrically connected to the D²PAK metal tab, which serves as the primary thermal path (RthJC ≈ 3 °C/W).
3	OUTPUT	power_out	Regulated +15 V output (Vo, tolerance ±4 % standard, ±2 % on A-grade). Delivers up to 1.5 A with adequate heat-sinking. Recommend a 0.1 µF output bypass capacitor to improve transient response.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`l7815cd2t-tr.step`	108 KB	You want the bare part, or you mark your own boards.
`l7815cd2t-tr-etched.step`	1.8 MB	You want the part with `L7815CD2T-TR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 465 faces against 79 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.
