MC78M15CDTG from onsemi, in a DPAK-3. 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 input supply. Absolute maximum 35 Vdc (40 Vdc for 20-24 V options). Must be at least ~2 V above the regulated output for the device to remain in regulation. A small input bypass capacitor is recommended when the device is located far from the filter capacitor. |
| 2 | Ground | power_in | Common ground reference for the regulator. The heatsink tab (terminal 4 in the case outline drawing) is internally connected to Pin 2 in the DPAK-3 package. |
| 3 | Output | power_out | Regulated +15 V output, typically 15.0 V (14.4 to 15.6 V over tolerance for MC78M15C). Sources up to 500 mA continuous with adequate heatsinking; short-circuit current limit typ. 350 mA. An output bypass capacitor improves transient response. |
| 4 | Heatsink/Ground | passive | Exposed heatsink tab on the DPAK package. Internally bonded to Pin 2 (Ground); solder to a copper pour for thermal dissipation. Not an independent electrical node. |
