HT7805ARMZ

HTCSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252

HT7805ARMZ from HTCSEMI, in a TO-252. 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 Input (1. Input).
2 GND power_in Ground reference for both input and output. Also serves as the thermal path via the package tab on TO-220/TO-252/TO-263 (tab is electrically connected to GND).
3 Output power_out Regulated 5 V output (3. Output).

Ordering variants

Same part, different packaging or reel option.

CAD (KiCad official)

  • Symbol: HT7805ARMZ
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252 (KiCad packages3D, STEP)
  • 3D model files: ht7805armz-etched.step / ht7805armz-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ht7805armz.step / ht7805armz.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
ht7805armz.step 119 KB You want the bare part, or you mark your own boards.
ht7805armz-etched.step 1.7 MB You want the part with HT7805ARMZ already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 440 faces against 83 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: HTCSEMI datasheet (6 pp, sha256 0749d78f58a6be2f, 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).
