LM7805S

HGSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-263-3

LM7805S from HGSEMI, in a TO-263-3. 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 VCC power_in Unregulated positive input supply. Absolute maximum VIN = 35 V; for +5 V output, recommended VI = 7.5 V to 35 V. A 0.33 uF ceramic bypass capacitor should be placed close to this pin to ground.
2 GND power_in Common ground reference for both input and output. On the TO-263 package this pin is electrically connected to the tab / thermal pad, which is also the primary heat-sink path.
3 OUT power_out Regulated +5.0 V output (4.80 V to 5.20 V at VI=10 V, Io=0.5 A). Capable of sourcing up to IOM = 1.2 A. A 0.1 uF ceramic (and optional 10 uF bulk) capacitor to ground is recommended for stability.

Ordering variants

Same part, different packaging or reel option.

  • LM7805SS/TR
  • LM7805ST

CAD (KiCad official)

  • Symbol: LM7805S
  • Footprint: Package_TO_SOT_SMD:TO-263-2
  • 3D model: TO-263-3 (KiCad packages3D, STEP)
  • 3D model files: lm7805s-etched.step / lm7805s-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm7805s.step / lm7805s.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lm7805s.step 108 KB You want the bare part, or you mark your own boards.
lm7805s-etched.step 1.4 MB You want the part with LM7805S already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 359 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: HGSEMI datasheet (11 pp, sha256 7c51292380972d4a, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
