MC78L15ABDR2G from onsemi, in a SOIC-8. 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	VOUT	power_out	Regulated +15 V output. Typical output 15 V (14.4 V min / 15.6 V max at TJ = 25 C), up to 100 mA. Recommend 0.1 uF ceramic to GND for transient response.
2	GND	power_in	Ground reference. SOIC-8 pins 2, 3, 6, and 7 are electrically common to the die-attach flag; tying all four together on the PCB copper improves thermal dissipation.
3	GND	power_in	Ground reference. Internally connected to die-attach flag along with pins 2, 6, 7. Tie all four ground pins to a copper ground pour for improved thermal performance.
4	NC	unconnected	No internal connection. Leave floating or tie to ground; not electrically connected to the die.
5	NC	unconnected	No internal connection. Leave floating or tie to ground; not electrically connected to the die.
6	GND	power_in	Ground reference. Internally common with pins 2, 3, 7 via the die-attach flag; connect all four to the ground pour for thermal dissipation.
7	GND	power_in	Ground reference. Internally common with pins 2, 3, 6 via the die-attach flag; connect all four to the ground pour for thermal dissipation.
8	VIN	power_in	Unregulated input supply. Must be at least ~1.7 V above VOUT (Vdrop ~ 1.7 V typ.); absolute maximum 30 V for the 15 V variant. Place a 0.33 uF input capacitor to GND if the regulator is located an appreciable distance from the power-supply filter.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mc78l15abdr2g.step`	122 KB	You want the bare part, or you mark your own boards.
`mc78l15abdr2g-etched.step`	2.5 MB	You want the part with `MC78L15ABDR2G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 627 faces against 147 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.
