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 DC input (V_I). Accepts up to 35 V absolute maximum for the 12 V output variant. A 0.33 uF ceramic capacitor to GND close to the pin is recommended for stability. |+| 2 | GROUND | power_in | Common ground / reference return. Electrically connected to the TO-220 metal tab; carries the quiescent current that flows out of the ground pin (I_Q is not part of the load current path). |+| 3 | OUTPUT | power_out | Regulated +12 V output, up to 1.5 A with adequate heat-sinking. A 0.1 uF ceramic capacitor to GND is recommended to improve transient response. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | TO-220 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `L7812CV-DG`+- `L7812CV-DGL7812CV`+- `L7812CV-DGL7812CP`+- `L7812CV-DGL7812CD2T-TR`++## CAD (KiCad official)++- Symbol: `L7812CV-DG`+- Footprint: `Package_TO_SOT_THT:TO-220-3_Vertical`+- 3D model: TO-220 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [STMicroelectronics datasheet](https://www.st.com/resource/en/datasheet/l7812cv-dg.pdf) (58 pp, sha256 `6c86513636f2d6c9`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
