MC7815CTG

onsemi · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220

MC7815CTG from onsemi, in a TO-220. 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 VI power_in Unregulated positive input voltage. For the 15 V output variant, VI must remain typically ~2.0 V above VO (dropout ≈ 2.0 V at 1.0 A); absolute maximum 35 Vdc. A 0.33 μF input capacitor is required if the regulator is located an appreciable distance from the supply filter.
2 GND power_in Common ground reference, shared between input and output. On the TO-220 T SUFFIX package the heatsink tab is electrically connected to Pin 2 (ground).
3 VO power_out Regulated positive output. Nominal +15 V (±4 % for MC7815C over 5.0 mA ≤ IO ≤ 1.0 A, 17.5 V ≤ VI ≤ 30 V typical range for the 15 V variant). Peak output current typ. 2.2 A; short-circuit current limit ~0.2 A at VI = 35 V. An output capacitor (CO, e.g. ≥0.1 μF) improves transient response.

CAD (KiCad official)

  • Symbol: MC7815CTG
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220 (KiCad packages3D, STEP)
  • 3D model files: mc7815ctg-etched.step / mc7815ctg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mc7815ctg.step / mc7815ctg.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
mc7815ctg.step 83 KB You want the bare part, or you mark your own boards.
mc7815ctg-etched.step 827 KB You want the part with MC7815CTG already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 217 faces against 48 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 (28 pp, sha256 a0831a3a6a3010ac, 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).
