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 | I | power_in | Unregulated input voltage. Recommended Vi ≥ 11.5V for 9V output; absolute maximum 35V. Bypass with a 0.33µF ceramic capacitor to GND close to the pin for stability. |+| 2 | G | power_in | Common ground reference for input and output. In the TO-220 package this pin is electrically connected to the metal tab (heatsink). |+| 3 | O | power_out | Regulated +9V output. Sources up to 1.2A with internal current limit (typ. 0.4A short-circuit). Bypass with a 0.1µF ceramic capacitor to GND to improve transient response. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | TO-220 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `L7809CVCV`++## CAD (KiCad official)++- Symbol: `L7809CV`+- 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/l7809cv-datasheet.pdf) (18 pp, sha256 `187ff89cc4c93f6a`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
