L7805ABV

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

L7805ABV from STMicroelectronics, 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 VI power_in Unregulated DC input voltage. Must be at least ~2 V above the nominal 5 V output (dropout) and no more than 35 V absolute maximum. A 0.33 µF bypass capacitor to GND close to the pin is recommended.
2 GND power_in Common ground reference for both input and output. On the TO-220FP the tab is electrically isolated from this pin (fully-plastic package), so the tab does not carry the ground potential.
3 VO power_out Regulated +5 V output, up to 1.5 A with adequate heat sinking. A 0.1 µF output capacitor to GND is recommended for transient response; internal current-limiting, thermal-shutdown and SOA protection make the output essentially indestructible.

CAD (KiCad official)

  • Symbol: L7805ABV
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220 (KiCad packages3D, STEP)
  • 3D model files: l7805abv-etched.step / l7805abv-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); l7805abv.step / l7805abv.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
l7805abv.step 83 KB You want the bare part, or you mark your own boards.
l7805abv-etched.step 756 KB You want the part with L7805ABV already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 200 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: STMicroelectronics datasheet (58 pp, sha256 b1d60dcc16599726, retrieved 2026-08-17, tier: manufacturer)
  • 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).
