LP2950CDT-5.0RKG 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 | Input | power_in | Unregulated input supply. Absolute max VCC = 30 Vdc (32 V peak transient <300 ms). A 1.0 µF bypass capacitor to ground is recommended if the input source is more than 4 inches of wire away from a battery or filter cap. |
| 2 | Ground | power_in | Device ground reference. The DPAK heatsink tab (mechanical terminal 4) is internally connected to this pin, so the mounting pad is at ground potential. |
| 3 | Output | power_out | Regulated 5.0 V output, capable of >100 mA. Requires a minimum 1.0 µF output capacitor for stability (aluminum, tantalum, or MLCC acceptable). Internal current limit typically 220 mA, with thermal shutdown protection. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 601 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.
