ME6231A50M3G

MICRONE · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT23-3

ME6231A50M3G from MICRONE, in a SOT23-3. 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 return for the regulator. Connect to the system ground plane; place the CIN/CL bypass capacitor grounds close to this pin to minimize noise and improve PSRR.
2 VOUT power_out Regulated 5.0 V output (±1% accuracy). Capable of sourcing up to 500 mA (typ) with 125 mV dropout at IOUT=100 mA. Requires a ceramic output capacitor CL (recommended 10 µF, X5R/X7R) to VSS; a 0.1 µF bypass is not required. Internal active discharge (~500 Ω) pulls VOUT low when the part is disabled internally.
3 VIN power_in Unregulated supply input, 3 V to 18 V operating range (20 V absolute max). Bypass to VSS with a 10 µF ceramic capacitor (X5R/X7R recommended). Quiescent current is 1.8 µA typical.

CAD (KiCad official)

  • Symbol: ME6231A50M3G
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT23-3 (KiCad packages3D, STEP)
  • 3D model files: me6231a50m3g-etched.step / me6231a50m3g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); me6231a50m3g.step / me6231a50m3g.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
me6231a50m3g.step 59 KB You want the bare part, or you mark your own boards.
me6231a50m3g-etched.step 2.3 MB You want the part with ME6231A50M3G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 549 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.
