L7815CV-DG

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

L7815CV-DG from STMicroelectronics, 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 INPUT power_in Unregulated DC input (V_I). Absolute maximum 35 V for the 15 V variant; recommended operating headroom of at least ~2 V above V_O. Bypass to GND with a 0.33 uF ceramic close to the pin to suppress input transients and ensure stability.
2 GROUND power_in Common ground return for the regulator. Electrically tied to the TO-220 metal tab/heatsink, so the tab is at GND potential. Carries the quiescent current plus the load return current.
3 OUTPUT power_out Regulated +15 V output (V_O), 2% tolerance for the A version. Supplies up to 1.5 A with adequate heatsinking. Decouple to GND with a 0.1 uF ceramic close to the pin to improve transient response and prevent oscillation.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
l7815cv-dg.step 83 KB You want the bare part, or you mark your own boards.
l7815cv-dg-etched.step 791 KB You want the part with L7815CV-DG already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 211 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: STMicroelectronics datasheet (58 pp, sha256 d975015f790fef7e, 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).
