MC78L05ABDR2G 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 +5.0 V output (4.8 V to 5.2 V at Tj=25 C). Sources up to 100 mA. A 0.1 uF output capacitor is recommended to improve transient response.
2	GND	power_in	Ground / common reference. Pins 2, 3, 6, and 7 are all electrically common to the internal die attach flag for improved thermal dissipation and must be tied to ground.
3	GND	power_in	Ground / common reference. Electrically common with pins 2, 6, 7 and the die attach flag; tie to ground plane to lower thermal resistance.
4	NC	unconnected	No internal connection. Leave floating or tie to GND at the user's discretion.
5	NC	unconnected	No internal connection. Leave floating or tie to GND at the user's discretion.
6	GND	power_in	Ground / common reference. Electrically common with pins 2, 3, 7 and the die attach flag; tie to ground plane for thermal dissipation.
7	GND	power_in	Ground / common reference. Electrically common with pins 2, 3, 6 and the die attach flag; tie to ground plane for thermal dissipation.
8	VIN	power_in	Unregulated positive input voltage. For the 5 V variant, absolute maximum is 30 V; typical operating range is 7.0 V to 20 V. Must remain ~2 V above VOUT even at the ripple valley. A 0.33 uF input capacitor is required if the regulator is located away from the power supply filter.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mc78l05abdr2g.step`	122 KB	You want the bare part, or you mark your own boards.
`mc78l05abdr2g-etched.step`	2.7 MB	You want the part with `MC78L05ABDR2G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 657 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.
