ME6118A33B3G

MICRONE · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223

ME6118A33B3G from MICRONE, in a SOT-223. 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 GND power_in Ground return / device reference (VSS). Also serves as the SOT-223 tab thermal pad in this package.
2 VOUT power_out Regulated 3.3V output (±2%). Supplies up to 1A (typ. 800mA guaranteed) with 680mV typ. dropout at 800mA. Requires ≥10µF ceramic output capacitor for stability.
3 VIN power_in Unregulated input supply. Operating range 2.5V to 18V (absolute maximum 18V). Requires ≥10µF ceramic input capacitor. Must be at least VOUT+VDROPOUT for regulation.

CAD (KiCad official)

  • Symbol: ME6118A33B3G
  • Footprint: Package_TO_SOT_SMD:SOT-223-3_TabPin2
  • 3D model: SOT-223 (KiCad packages3D, STEP)
  • 3D model files: me6118a33b3g-etched.step / me6118a33b3g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); me6118a33b3g.step / me6118a33b3g.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
me6118a33b3g.step 64 KB You want the bare part, or you mark your own boards.
me6118a33b3g-etched.step 2.5 MB You want the part with ME6118A33B3G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 607 faces against 75 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 (17 pp, sha256 a7f450566318afe8, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
