MC78M12ABDTRKG

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.

CAD (KiCad official)

  • Symbol: MC78M12ABDTRKG
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: DPAK-3 (KiCad packages3D, STEP)
  • 3D model files: mc78m12abdtrkg-etched.step / mc78m12abdtrkg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mc78m12abdtrkg.step / mc78m12abdtrkg.glb are the bare package body.

Provenance
