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 | VI | power_in | Unregulated positive input voltage. Absolute max input 35 V (for VO=5-18V variants). A 0.33 µF input bypass capacitor is recommended near the pin to suppress oscillation when the regulator is located far from the raw supply filter. |+| 2 | GND | power_in | Common ground reference for both input and output. On the TO-220 package this pin is electrically connected to the metal tab, so the tab must be treated as GND when heatsinking. |+| 3 | VO | power_out | Regulated +12 V output (typ; 11.4-12.6 V over line/load). Delivers up to 1.2 A with adequate heatsinking. A 0.1 µF ceramic output capacitor is recommended for transient response; larger tantalum/electrolytic caps improve stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | TO-220 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `L7812CVCV`+- `L7812CVD2T`+- `L7812CVDT`++## CAD (KiCad official)++- Symbol: `L7812CV`+- 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:** [UMW datasheet](docs/l7812cv-datasheet.pdf) (18 pp, sha256 `187ff89cc4c93f6a`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
