LM7805CT

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

LM7805CT from HGSEMI, 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 positive input supply. For the 5 V (LM7805C) variant the recommended input range is 7 V to 25 V, absolute maximum 35 V. A 0.33 uF bypass capacitor to GND is recommended close to the pin.
2 OUTPUT power_out Regulated +5 V positive output. Delivers up to 1.5 A with adequate heat sinking; internally current-limited and thermally protected. A 0.1 uF output capacitor to GND is recommended for stability.
3 GND power_in Common ground reference for input and output. On the TO-220-3 package the ground pin is also thermally/electrically connected to the metal tab.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lm7805ct.step 83 KB You want the bare part, or you mark your own boards.
lm7805ct-etched.step 740 KB You want the part with LM7805CT already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 196 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: HGSEMI datasheet (16 pp, sha256 f70b2e22c7f5c571, 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).
