MC78M08CDTRKG

onsemi · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DPAK-3

MC78M08CDTRKG 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 VIN power_in Unregulated positive input voltage. For the 8 V (M08) variant, VI operates from 10.5 V to 25 V (absolute maximum 35 V). A ≥0.33 µF bypass capacitor to ground is recommended when the device is located far from the supply filter capacitor.
2 GND power_in Common ground return for input and output. In the DPAK (DT/Case 369C) package this pin is electrically connected to the exposed heatsink tab (terminal 4), so the tab is also at ground potential.
3 VOUT power_out Regulated +8.0 V output, up to 500 mA (700 mA peak) with adequate heatsinking. Output tolerance is ±4% (MC78M08C) / ±2% (MC78M08AC). A ≥0.1 µF output capacitor is recommended to improve transient response.

CAD (KiCad official)

  • Symbol: MC78M08CDTRKG
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: DPAK-3 (KiCad packages3D, STEP)
  • 3D model files: mc78m08cdtrkg-etched.step / mc78m08cdtrkg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mc78m08cdtrkg.step / mc78m08cdtrkg.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
mc78m08cdtrkg.step 119 KB You want the bare part, or you mark your own boards.
mc78m08cdtrkg-etched.step 2.2 MB You want the part with MC78M08CDTRKG already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 560 faces against 83 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
