ME1117A33K3G

MICRONE · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2

ME1117A33K3G from MICRONE, in a TO-252-2. 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 VSS power_in Ground return. Also serves as the thermal reference for the die; tie to the system ground plane with a low-impedance path.
2 VOUT power_out Regulated 3.3V output, up to 1.0A (1.3A current limit). Requires a 10µF output capacitor to ground for stability.
3 VIN power_in Unregulated supply input, 4.8V to 15V operating (20V absmax). Requires a 10µF input capacitor to ground close to the pin.

CAD (KiCad official)

  • Symbol: ME1117A33K3G
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252-2 (KiCad packages3D, STEP)
  • 3D model files: me1117a33k3g-etched.step / me1117a33k3g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); me1117a33k3g.step / me1117a33k3g.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
me1117a33k3g.step 119 KB You want the bare part, or you mark your own boards.
me1117a33k3g-etched.step 2.0 MB You want the part with ME1117A33K3G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 517 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: MICRONE datasheet (13 pp, sha256 e26fed9e4d5c980c, 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).
