78L06-150 from UMW, in a SOT-89-3. 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 +6 V output. Typical Vo = 6.0 V (5.94-6.06 V at Tj=25 °C). Deliver up to 150 mA; place a 0.1 µF ceramic to GND close to the pin for stability.
2	GND	power_in	Ground / common return for the regulator. Serves as the reference for both Vin and Vout; also the thermal path of the SOT-89 package (pin 2 = tab).
3	INPUT	power_in	Unregulated positive supply input. For Vo=6 V variant the input must be ≥ ~8 V (Vin ≥ Vout + 1.7 V dropout) and ≤ 35 V absolute maximum. Decouple with a 0.33 µF ceramic to GND close to the pin.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`78l06-150.step`	57 KB	You want the bare part, or you mark your own boards.
`78l06-150-etched.step`	1.4 MB	You want the part with `78L06-150` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 358 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.
