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, VI. Recommended operating range up to 35 V (absolute max 35 V; 40 V for short 20-24 V transient conditions). For the +15 V variant, VI must exceed VO by ~2 V dropout (typ 17.5 V min). |+| 2 | Ground | power_in | Common ground reference for input and output. The DPAK heatsink tab (terminal 4 in the case outline drawing) is internally connected to Pin 2. |+| 3 | Output | power_out | Regulated +15 V output (14.4 V to 15.6 V over line/load/temperature; 15.0 V typ). Rated 500 mA continuous with adequate heatsinking; short-circuit current limit 350 mA typ; peak output current 700 mA typ. |+| 4 | Tab/Heatsink | passive | Exposed thermal pad (heatsink tab) shown as terminal 4 in the DPAK case outline drawing. Internally connected to Pin 2 (Ground). Solder to a copper ground pour for heat dissipation. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | DPAK-3 |+| Category | PMIC |+| Pins | 4 |++## Ordering variants++- `MC78M15CDTRKGDTRKG`+- `MC78M15CDTRKGDTG`+- `MC78M15CDTRKGTG`++## CAD (KiCad official)++- Symbol: `MC78M15CDTRKG`+- Footprint: `Package_TO_SOT_SMD:TO-252-2`+- 3D model: DPAK-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [onsemi datasheet](https://www.onsemi.com/pdf/datasheet/mc78m15cdtrk-d.pdf) (15 pp, sha256 `2339bbc0a38dcd3b`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
