MC7805CDTRKG

onsemi · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2(DPAK)

MC7805CDTRKG from onsemi, in a TO-252-2(DPAK). 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. Recommended input range 7.0 V to 25 V (abs-max 35 V for MC7805C). A 0.33 uF ceramic input capacitor (Cin) is recommended when the regulator is located an appreciable distance from the power supply filter.
2 GND power_in Common ground reference shared between input and output. Also serves as the thermal path; the DPAK exposed tab (terminal 4 in the case outline drawing) is internally connected to Pin 2.
3 Vout power_out Regulated +5.0 V output (Vo min 4.8 V, typ 5.0 V, max 5.2 V for MC7805C at Tj = 25 C). Output can deliver in excess of 1.0 A with adequate heatsinking; short-circuit current typically 0.6 A at Vin = 35 V. Optional Co (>= 0.1 uF) improves transient response.
4 TAB power_in DPAK exposed heatsink tab. Internally connected to Pin 2 (Ground). Solder to a ground copper pour to spread heat; junction-to-case thermal resistance is 5.0 C/W.

CAD (KiCad official)

  • Symbol: MC7805CDTRKG
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252-2(DPAK) (KiCad packages3D, STEP)
  • 3D model files: mc7805cdtrkg-etched.step / mc7805cdtrkg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mc7805cdtrkg.step / mc7805cdtrkg.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
mc7805cdtrkg.step 119 KB You want the bare part, or you mark your own boards.
mc7805cdtrkg-etched.step 2.0 MB You want the part with MC7805CDTRKG already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 514 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 (31 pp, sha256 ad3f70896343dcf0, 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).
