L7915CV from STMicroelectronics, in a TO-220. 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	Common ground reference. Connect to the 0 V rail of the split supply. Return path for the regulator's quiescent current.
2	IN	power_in	Unregulated negative input supply. Absolute maximum VI = -35 V for -5 V to -18 V output variants (includes -15 V). Requires a bypass capacitor to GND close to the pin (typ. 2.2 uF electrolytic) for stability.
3	OUT	power_out	Regulated -15 V output, capable of sourcing up to 1.5 A with adequate heatsinking. Requires an output capacitor to GND (typ. 1 uF tantalum or 10 uF electrolytic) for transient response and stability.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`l7915cv.step`	83 KB	You want the bare part, or you mark your own boards.
`l7915cv-etched.step`	582 KB	You want the part with `L7915CV` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 158 faces against 48 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.
