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 | VIN | power_in | Unregulated DC input voltage. For the 12V variant, VI up to 35V absolute max; recommended operating range ~14.5V to 30V. Bypass to GND with 0.33µF ceramic close to the pin. |+| 2 | GND | power_in | Common ground reference. Electrically connected to the exposed TAB of the TO-252-2 package; solder the TAB to a copper pour for both grounding and heatsinking. |+| 3 | VOUT | power_out | Regulated +12V output (11.75V-12.25V typical at TJ=25°C), up to 0.5A with adequate heatsinking. Bypass to GND with a 0.1µF ceramic close to the pin for stability. |+| TAB | GND | power_in | Exposed thermal/electrical tab, internally tied to GND (pin 2). Solder to a ground copper pour to conduct heat away from the die. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI |+| Package | TO-252-2 |+| Category | PMIC |+| Pins | 4 |++## Ordering variants++- `LM78M12CDTCDT`+- `LM78M12CDTCDT/TR`+- `LM78M12CDTMP`+- `LM78M12CDTMP/TR`++## CAD (KiCad official)++- Symbol: `LM78M12CDT`+- Footprint: `Package_TO_SOT_SMD:TO-252-2`+- 3D model: TO-252-2 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HGSEMI datasheet](docs/lm78m12cdt-datasheet.pdf) (13 pp, sha256 `8144e826c281aa11`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
