L7805CV

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

L7805CV 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 5 V output devices, VI must be at least ~7 V and not exceed 35 V (absolute max). A 0.33 µF ceramic bypass capacitor to GND is recommended close to the pin.
2 GND power_in Common ground reference for the input and output. The tab of the TO-220 package is electrically connected to this pin and serves as the thermal/heat-sink path.
3 OUT power_out Regulated +5 V output, typically 5 V (4.8-5.2 V at TJ=25 °C) with up to 1.2 A load capability. A 0.1 µF ceramic capacitor to GND at the pin is recommended for stability and transient response.

CAD (KiCad official)

  • Symbol: L7805CV
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220 (KiCad packages3D, STEP)
  • 3D model files: l7805cv-etched.step / l7805cv-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); l7805cv.step / l7805cv.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
l7805cv.step 83 KB You want the bare part, or you mark your own boards.
l7805cv-etched.step 686 KB You want the part with L7805CV already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 180 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).
