MC78M15CDTRKG

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

MC78M15CDTRKG 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 DC input, VI. Recommended operating range up to 35 V (absolute max 35 V; 40 V for short 20-24 V transient conditions). For the +15 V variant, VI must exceed VO by ~2 V dropout (typ 17.5 V min).
2 Ground power_in Common ground reference for input and output. The DPAK heatsink tab (terminal 4 in the case outline drawing) is internally connected to Pin 2.
3 Output power_out Regulated +15 V output (14.4 V to 15.6 V over line/load/temperature; 15.0 V typ). Rated 500 mA continuous with adequate heatsinking; short-circuit current limit 350 mA typ; peak output current 700 mA typ.
4 Tab/Heatsink passive Exposed thermal pad (heatsink tab) shown as terminal 4 in the DPAK case outline drawing. Internally connected to Pin 2 (Ground). Solder to a copper ground pour for heat dissipation.

Two STEP files. Same geometry, different body top:

File Size Use it when
mc78m15cdtrkg.step 119 KB You want the bare part, or you mark your own boards.
mc78m15cdtrkg-etched.step 2.0 MB You want the part with MC78M15CDTRKG already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 522 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 (15 pp, sha256 2339bbc0a38dcd3b, 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).
