MC7805BDTRKG from onsemi, in a TO-252-2(DPAK). 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 | VI | power_in | Unregulated positive input supply. Must remain at least ~2.0 V above the 5.0 V output (dropout typ 2.0 V at Io = 1.0 A). Absolute-maximum input voltage 35 Vdc (40 Vdc for the 24 V variant). A 0.33 uF ceramic input cap (Cin) is recommended if the regulator sits any appreciable distance from the bulk supply filter. |
| 2 | GND | power_in | Common ground reference shared by input and output. On DPAK-3 / D2PAK-3 packages the exposed heatsink tab is internally connected to this pin, so the mounting pad is at ground potential and can be soldered directly to the PCB ground plane for heat dissipation. |
| 3 | VO | power_out | Regulated +5.0 V output, 4.8-5.2 V over Tj = 25 °C for the 'B' grade, capable of >1.0 A with adequate heatsinking (peak Imax typ 2.2 A, Isc typ 0.2 A at Vin = 35 V). An output capacitor (Co, typically >=0.1 uF) is not required for stability but improves transient response; smaller values may cause instability. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 530 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.
