L7815CV

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

L7815CV from UMW, 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 IN power_in Unregulated positive input voltage. For the 15V output variant the input range is typically 17.5V to 30V (absolute max Vi=35V). A 0.33µF bypass capacitor to GND is recommended close to the pin.
2 GND power_in Common ground reference. Also serves as the thermal path via the tab (electrically connected to GND on TO-220).
3 OUT power_out Regulated +15V output (4.75-5.25V tolerance scaled to 15V, i.e. ~14.25-15.75V over line/load). Output current up to 1.2A. A 0.1µF ceramic capacitor to GND is recommended for stability.

Same part, different packaging or reel option.

  • L7815CV

CAD (KiCad official)

  • Symbol: L7815CV
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220 (KiCad packages3D, STEP)
  • 3D model files: l7815cv-etched.step / l7815cv-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); l7815cv.step / l7815cv.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
l7815cv.step 83 KB You want the bare part, or you mark your own boards.
l7815cv-etched.step 615 KB You want the part with L7815CV already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 165 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: UMW datasheet (18 pp, sha256 187ff89cc4c93f6a, retrieved 2026-08-17, tier: lcsc)
  • 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).
