LM2931ADT50R from STMicroelectronics, in a DPAK. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VOUT | power_out | Regulated output of the fixed 5 V version, which delivers up to 100 mA and is protected by internal current and thermal limiting. |
| 2 | GND | power_in | Ground reference pin of the regulator. |
| 3 | VIN | power_in | Unregulated input supply, with a maximum operating input voltage of 26 V, a 40 V maximum DC input rating, and a 60 V load dump transient rating (under 100 ms). |
