LM7805S2

HGSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-263-2

LM7805S2 from HGSEMI, in a TO-263-2. 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 (VI). Recommended input range 7.5 V to 35 V for the 5 V variant; absolute maximum VIN = 35 V. Bypass with a 0.33 uF capacitor close to the pin.
2 GND power_in Ground / common reference. Also connects to the exposed tab of the TO-263-2 package.
3 OUT power_out Regulated +5.0 V output (4.80-5.20 V typical). Maximum output current IOM = 1.2 A. Bypass with a 0.1 uF capacitor (and optional 10 uF bulk) close to the pin.

Two STEP files. Same geometry, different body top:

File Size Use it when
lm7805s2.step 108 KB You want the bare part, or you mark your own boards.
lm7805s2-etched.step 1.5 MB You want the part with LM7805S2 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 397 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.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
