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). Absolute maximum 35 V for the 15 V variant; recommended operating headroom of at least ~2 V above V_O. Bypass to GND with a 0.33 uF ceramic close to the pin to suppress input transients and ensure stability. |+| 2 | GROUND | power_in | Common ground return for the regulator. Electrically tied to the TO-220 metal tab/heatsink, so the tab is at GND potential. Carries the quiescent current plus the load return current. |+| 3 | OUTPUT | power_out | Regulated +15 V output (V_O), 2% tolerance for the A version. Supplies up to 1.5 A with adequate heatsinking. Decouple to GND with a 0.1 uF ceramic close to the pin to improve transient response and prevent oscillation. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | TO-220 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `L7815CV-DGCV`+- `L7815CV-DGCV-DG`+- `L7815CV-DGCP`+- `L7815CV-DGCDT`+- `L7815CV-DGCD2T`++## CAD (KiCad official)++- Symbol: `L7815CV-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/l7815cv-dg.pdf) (58 pp, sha256 `d975015f790fef7e`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
