L7805CD2T

UMW · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-263

L7805CD2T from UMW, in a TO-263. 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 DC input. Recommended 7 V to 25 V for 5 V output; absolute maximum 35 V. A 0.33 µF ceramic input decoupling capacitor to GND is recommended close to the pin to ensure stability.
2 GND power_in Common ground for both input and output. On TO-252 (DPAK) this pin is electrically connected to the exposed thermal tab, which should be soldered to a copper heatsink pad to dissipate power (RthJC = 8 °C/W, RthJA = 100 °C/W for TO-252).
3 OUT power_out Regulated +5 V output (4.8 V-5.2 V typ. at TJ=25 °C, IO=500 mA). Sources up to 1.2 A subject to thermal and SOA limits. A 0.1 µF ceramic output capacitor to GND is recommended for transient response and stability.

CAD (KiCad official)

  • Symbol: L7805CD2T
  • Footprint: Package_TO_SOT_SMD:TO-263-2
  • 3D model: TO-263 (KiCad packages3D, STEP)
  • 3D model files: l7805cd2t-etched.step / l7805cd2t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); l7805cd2t.step / l7805cd2t.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
l7805cd2t.step 108 KB You want the bare part, or you mark your own boards.
l7805cd2t-etched.step 1.6 MB You want the part with L7805CD2T already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 418 faces against 79 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).
