LM7808CT

HGSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220-3

LM7808CT from HGSEMI, in a TO-220-3. 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 IN power_in Unregulated positive input voltage. Recommended VI = 14 V for 8 V output; absolute max 35 V. Bypass to GND with a 0.33 uF ceramic capacitor close to the pin.
2 OUT power_out Regulated +8 V output (typ, 7.7-8.3 V at TJ=25 degC). Sources up to 1.5 A peak (1 A continuous with adequate heatsinking). Bypass to GND with a 0.1 uF ceramic capacitor for stability.
3 GND power_in Common ground return for input and output. Tab of TO-220-3 is electrically connected to GND (pin 3).

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lm7808ct.step 83 KB You want the bare part, or you mark your own boards.
lm7808ct-etched.step 791 KB You want the part with LM7808CT already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 206 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).
