ME6118A43B3G

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

ME6118A43B3G 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 Device ground / common return. Reference for the internal bandgap and feedback divider that sets the 4.3V output. Tab of the SOT-223 is internally tied to GND (pin 1) and should be soldered to a copper pour for heat spreading.
2 VOUT power_out Regulated 4.3V output (±2%). Sources up to 1A continuous with a typical dropout of ~665mV at 400mA and ~1250mV at 800mA. Requires a 10µF ceramic output capacitor (CL) for stability.
3 VIN power_in Unregulated input supply, VOUT+1.3V (dropout headroom) up to 18V absolute max. A 10µF ceramic input capacitor (CIN) is required close to this pin.

Two STEP files. Same geometry, different body top:

File Size Use it when
me6118a43b3g.step 64 KB You want the bare part, or you mark your own boards.
me6118a43b3g-etched.step 2.4 MB You want the part with ME6118A43B3G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 578 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 (22 pp, sha256 b356c56c07463946, 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).
