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 positive supply input (Vi). Absolute maximum 35 V for the 15 V version; typical operating range ≈17 V to 30 V. Recommend a 0.33 µF bypass capacitor from INPUT to GND close to the device. |+| 2 | GROUND | power_in | Common ground / return pin. Electrically connected to the D²PAK metal tab, which serves as the primary thermal path (RthJC ≈ 3 °C/W). |+| 3 | OUTPUT | power_out | Regulated +15 V output (Vo, tolerance ±4 % standard, ±2 % on A-grade). Delivers up to 1.5 A with adequate heat-sinking. Recommend a 0.1 µF output bypass capacitor to improve transient response. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | D2PAK |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `L7815CD2T-TRCD2T-TR`+- `L7815CD2T-TRCD2T`+- `L7815CD2T-TRCV`+- `L7815CD2T-TRACV`+- `L7815CD2T-TRCP`+- `L7815CD2T-TRACP`+- `L7815CD2T-TRCDT-TR`+- `L7815CD2T-TRCDT`++## CAD (KiCad official)++- Symbol: `L7815CD2T-TR`+- Footprint: `Package_TO_SOT_SMD:TO-263-2`+- 3D model: D2PAK (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [STMicroelectronics datasheet](https://www.st.com/resource/en/datasheet/l7815cd2t-tr.pdf) (55 pp, sha256 `f7b390b5c05e0aba`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
