Pinout and pin descriptions extracted from the datasheet (via LCSC) by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | INPUT | power_in | Unregulated positive DC input supply. Absolute maximum 35V (up to 40V on 24V variant); recommended input range for the 12V option is ~14.5V to 27V (dropout ~2V typ at 500mA). A 0.33uF ceramic bypass capacitor to GND is required close to this pin. |+| 2 | GND | power_in | Common ground reference for input and output. In the TO-252/SOT-223 package this pin is bonded to the tab / thermal pad and is the primary thermal path (θJC = 12.5 °C/W for TO-252, 15 °C/W for SOT-223). |+| 3 | OUTPUT | power_out | Regulated +12V DC output, 11.52 V to 12.48 V at 25°C (Io = 5 mA to 350 mA, Vi = 19V). Sources up to 1A continuous; internally current-limited (Isc ≈ 800 mA at Vi = 35V) and thermally protected. A 0.1uF output capacitor is recommended for stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW Youtai Semiconductor Co   Ltd |+| Package | TO-252 |+| Category | PMIC |+| Pins | 3 |++## CAD (KiCad official)++- Symbol: `78M12`+- 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:** [UMW Youtai Semiconductor Co   Ltd datasheet](https://datasheet.lcsc.com/datasheet/pdf/b6785ab63adcbf12f20510611436a8a6.pdf) (16 pp, sha256 `162df1416fa16ead`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
