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 | IN | power_in | Unregulated positive input supply. Accepts up to 35V absolute maximum; recommended operating range approximately 14.5V to 30V for a 12V output. Bypass to GND with a 0.33μF capacitor close to the pin. |+| 2 | GND | power_in | Common ground reference for input and output. Internally connected to the tab/heat slug of the TO-252 package, providing the primary thermal path to the PCB. |+| 3 | OUT | power_out | Regulated +12V output. Nominal 12V ±0.5V at Io=5-350mA, up to 500mA maximum (IOM 0.5A). Bypass to GND with a 0.1μF capacitor close to the pin for stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MSKSEMI |+| Package | TO-252 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `78M12-MS`++## CAD (KiCad official)++- Symbol: `78M12-MS`+- Footprint: `Package_TO_SOT_SMD:TO-252-2`+- 3D model: TO-252 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [MSKSEMI datasheet](docs/78m12-ms-datasheet.pdf) (None pp, sha256 `1b6f97415c0f51d6`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
