78D06L from UMW, in a TO-252-2. 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	INPUT	power_in	Unregulated positive supply input. Absolute max Vin = 35 V (for Vo=5..18 V variants). Recommended input capacitor Ci = 0.33 µF placed close to the pin. For 6 V output, typical Vin is 8..21 V with 2 V minimum dropout at Io = 500 mA.
2	GND	power_in	Common ground / reference return for both input and output. On TO-252 / TO-252-3 / SOT-223 this pin is also the thermal tab (soldered to PCB copper pour for heat dissipation, θJC = 12.5 °C/W for TO-25x, 15 °C/W for SOT-223).
3	OUTPUT	power_out	Regulated +6 V output (typ, 5.76..6.24 V at 25 °C, Io = 350 mA). Output current up to 1 A with proper heat-sinking; short-circuit current ~800 mA; peak current 1.3 A. Recommended output capacitor Co = 0.1 µF for stability.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`78d06l.step`	119 KB	You want the bare part, or you mark your own boards.
`78d06l-etched.step`	1.3 MB	You want the part with `78D06L` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 332 faces against 83 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.
