onsemi · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DPAK-3
MC78M12ABDTRKG from onsemi, in a DPAK-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Input | power_in | Unregulated input voltage to the regulator; the datasheet gives a maximum input voltage of 35 Vdc for the 5.0 V to 18 V option group. |
| 2 | Ground | power_in | Common ground terminal, which is also electrically connected to the heatsink surface (terminal 4 in the case outline). |
| 3 | Output | power_out | Regulated 12 V output; maximum output current with adequate heatsinking is 500 mA, with internal current limiting and thermal shutdown. |
