78L06MG-AB3-R from UTC Unisonic Tech, 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 | OUT | power_out | Regulated +6V output. Delivers up to 200mA with typical dropout of 1.7V. A 0.1uF ceramic bypass capacitor to GND is recommended close to the pin for stability and transient response. |
| 2 | GND | power_in | Ground reference for the regulator. On SOT-89 this pin also serves as the primary thermal path via the tab. |
| 3 | IN | power_in | Unregulated input voltage. For the 6V version, recommended operating range is 8.5V to 20V (absolute maximum 30V). A 0.33uF bypass capacitor to GND is recommended close to the pin. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 480 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.
