L7805CDT

UMW · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252

L7805CDT from UMW, in a TO-252. 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 I power_in Unregulated input voltage. Accepts 7 V to 25 V (35 V absolute max) for the 5 V output part; a 0.33 µF ceramic bypass capacitor to GND is recommended close to the pin.
2 G power_in Common ground reference for both the input and the output. On the TO-252 (DPAK) package the tab is electrically connected to this pin.
3 O power_out Regulated +5 V output (4.8 V-5.2 V typ. at TJ=25 °C), up to 1.2 A. A 0.1 µF ceramic capacitor to GND close to the pin is recommended for stability.

CAD (KiCad official)

  • Symbol: L7805CDT
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252 (KiCad packages3D, STEP)
  • 3D model files: l7805cdt-etched.step / l7805cdt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); l7805cdt.step / l7805cdt.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
l7805cdt.step 119 KB You want the bare part, or you mark your own boards.
l7805cdt-etched.step 1.4 MB You want the part with L7805CDT already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 373 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: 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).
