ME6231A33M3G

MICRONE · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

ME6231A33M3G from MICRONE, in a SOT-23-3. 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 / negative supply return for the regulator. Connect directly to the system ground plane; the input and output decoupling capacitor return currents should share this node with a low-impedance path.
2 VOUT power_out Regulated 3.3 V output pin. Sources up to 500 mA (typ) with ±1% accuracy; requires a ≥1 µF (10 µF recommended, X5R/X7R ceramic) output capacitor for stability and transient response. Internally clamped by active-discharge FET when the regulator is disabled.
3 VIN power_in Unregulated input supply, 3 V to 18 V operating range (20 V absolute max). Decouple to VSS with a ≥1 µF (10 µF recommended) X5R/X7R ceramic capacitor placed close to the pin. VOUT + 1 V minimum headroom is needed to stay out of dropout at rated load.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
me6231a33m3g.step 59 KB You want the bare part, or you mark your own boards.
me6231a33m3g-etched.step 2.4 MB You want the part with ME6231A33M3G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 569 faces against 69 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 (11 pp, sha256 ed816d826236b3bb, 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).
