MC78M05CDTRKG

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

MC78M05CDTRKG 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. Recommended operating range 7.0 V to 25 Vdc for the 5.0 V variant; absolute max 35 Vdc. A ~0.33 uF bypass capacitor is recommended close to the pin when the device is far from the main filter capacitor.
2 Ground power_in Common return / ground reference for both input and output. In the DPAK-3 package the heatsink tab (terminal 4 in the case outline) is internally connected to this pin.
3 Output power_out Regulated +5.0 V output, 500 mA maximum with adequate heatsinking (typical VO 5.0 V, tolerance +/-4% over line/load/temperature for the C grade). Dropout voltage typ 2.0 V. A ~0.1 uF output capacitor is recommended for transient response.
4 Ground (Tab) power_in Heatsink tab on the DPAK-3 package outline. Internally shorted to Pin 2 (Ground); commonly soldered to a copper pour to spread heat.

CAD (KiCad official)

  • Symbol: MC78M05CDTRKG
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: DPAK-3 (KiCad packages3D, STEP)
  • 3D model files: mc78m05cdtrkg-etched.step / mc78m05cdtrkg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mc78m05cdtrkg.step / mc78m05cdtrkg.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
mc78m05cdtrkg.step 119 KB You want the bare part, or you mark your own boards.
mc78m05cdtrkg-etched.step 2.1 MB You want the part with MC78M05CDTRKG already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 538 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.
