ME6239A33M3G

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

ME6239A33M3G from MICRONE, in a SOT-23. 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 for the LDO. Connect to system ground.
2 VOUT power_out Regulated voltage output. Fixed 3.3V for the A33 option (accuracy ±1%). Capable of sourcing up to 250mA when VIN >= VOUT+1.5V. Bypass with a low-ESR ceramic capacitor (10uF X5R/X7R typical); use 20~100uF to suppress overshoot on fast VIN transients.
3 VIN power_in Unregulated supply input. Operating range up to 30V absolute maximum. Bypass with a 10uF ceramic capacitor; use an electrolytic or tantalum input cap when VIN > 15V to absorb hot-plug/turn-on spikes that could otherwise exceed 40V and damage the device.

Two STEP files. Same geometry, different body top:

File Size Use it when
me6239a33m3g.step 59 KB You want the bare part, or you mark your own boards.
me6239a33m3g-etched.step 2.5 MB You want the part with ME6239A33M3G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 598 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.
