79L08 from Shikues, in a SOT-89. 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 for the regulator. For a negative regulator this pin is the 0V system reference; the input and output pins sit at negative voltages relative to GND.
2	IN	power_in	Negative unregulated input voltage (V_I). For 79L08 the operating input range is -10.5V to -23V (absolute max -35V). Recommended input decoupling capacitor C_i = 0.33 µF.
3	OUT	power_out	Regulated negative output voltage V_O = -8V (typ, -7.7V to -8.3V at Tj=25°C). Rated output current up to 150mA. Recommended output capacitor C_o = 0.1 µF.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`79l08.step`	57 KB	You want the bare part, or you mark your own boards.
`79l08-etched.step`	960 KB	You want the part with `79L08` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 254 faces against 42 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.
