ME6239A50M3G

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

ME6239A50M3G 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 reference (0V) for the regulator. Connect to system ground.
2 VOUT power_out Regulated 5.0V output (±1%) capable of sourcing up to 250mA. Requires a low-ESR ceramic output capacitor (10uF X5R/X7R typical) for stability; 20-100uF may be added to suppress output overshoot.
3 VIN power_in Unregulated power supply input, 5.0V to 30V operating range (30V absolute maximum). Requires a 10uF input capacitor; use electrolytic or tantalum instead of ceramic when VIN > 15V to absorb hot-plug voltage spikes that may exceed 40V.

CAD (KiCad official)

  • Symbol: ME6239A50M3G
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: me6239a50m3g-etched.step / me6239a50m3g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); me6239a50m3g.step / me6239a50m3g.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
me6239a50m3g.step 59 KB You want the bare part, or you mark your own boards.
me6239a50m3g-etched.step 2.4 MB You want the part with ME6239A50M3G 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 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 (8 pp, sha256 409f8e590878e966, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • 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).
