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 | VIN | power_in | Unregulated positive input voltage. For the +15 V variant (MC7815) the recommended input range is 17.5 V to 30 V (V_IN must stay ~2.0 V above V_OUT for regulation; absolute max 35 V). A ~0.33 µF ceramic bypass cap is recommended if the device is located far from the bulk filter capacitor. |+| 2 | GND | power_in | Common ground reference shared between the input and output loops. The exposed heatsink tab (shown as terminal 4 in the case outline drawing) is internally connected to this pin, so the mounting pad is at ground potential. |+| 3 | VOUT | power_out | Regulated positive output. Nominal +15 V, ±2 % (B-grade) at I_O = 500 mA, T_J = 25 °C; delivers up to 1.0 A with adequate heatsinking (short-circuit current limit ~0.2 A at V_IN = 35 V, peak output current ~2.2 A). Output cap C_O is optional for stability but improves transient response; values below 0.1 µF may cause instability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | TO-252-2(DPAK) |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `MC7815BDTRKGD2TRKG`+- `MC7815BDTRKGD2TR4KG`+- `MC7815BDTRKGD2TG`+- `MC7815BDTRKGTG`+- `MC7815BDTRKGT`+- `MC7815BDTRKGDTRKG`+- `MC7815BDTRKGDTG`++## CAD (KiCad official)++- Symbol: `MC7815BDTRKG`+- Footprint: `Package_TO_SOT_SMD:TO-252-2`+- 3D model: TO-252-2(DPAK) (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [onsemi datasheet](https://www.onsemi.com/pdf/datasheet/mc7815bdtrk-d.pdf) (30 pp, sha256 `8f5e68f22006fe8f`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
