MC79M15CDTRKG

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

MC79M15CDTRKG 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 GND power_in Common ground reference. A common ground is required between the input and output voltages.
2 VI power_in Negative input voltage. Absolute maximum −35 Vdc. For −15 V output operation, VI must remain typically 1.1 V more negative than VO (i.e., roughly −16.1 V minimum) even during input ripple peaks. Recommend 0.33 μF bypass capacitor (Cin) when regulator is located an appreciable distance from the power supply filter.
3 VO power_out Regulated −15 V negative output (−14.4 V to −15.6 V at TJ=25°C; 4% tolerance grade). Sources up to 500 mA with adequate heatsinking. Recommend 1.0 μF output capacitor (CO) to improve stability and transient response.
4 TAB power_in Exposed metal tab on the DPAK-3 body, electrically connected to the ground pin (pin 1). Provides thermal path to the PCB copper for heat dissipation; solder to a copper pour connected to GND.

CAD (KiCad official)

  • Symbol: MC79M15CDTRKG
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: DPAK-3 (KiCad packages3D, STEP)
  • 3D model files: mc79m15cdtrkg-etched.step / mc79m15cdtrkg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mc79m15cdtrkg.step / mc79m15cdtrkg.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
mc79m15cdtrkg.step 119 KB You want the bare part, or you mark your own boards.
mc79m15cdtrkg-etched.step 2.0 MB You want the part with MC79M15CDTRKG already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 515 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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: onsemi datasheet (9 pp, sha256 cab487486a5292f6, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
