ME6228A33PG

MICRONE · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

ME6228A33PG from MICRONE, in a SOT-89-3. 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 (地). Connect to system ground; forms the return path for both the input and output current.
2 VIN power_in Power supply input (电源输入端). Accepts 3.3 V to 30 V for the A33 variant (VIN must be ≥ VOUT + dropout ≈ VOUT + 1.5 V for full 150 mA regulation). Bypass with a 10 uF input capacitor; if VIN exceeds 15 V, use an electrolytic or tantalum input capacitor because the ceramic cap alone causes severe inrush spikes.
3 VOUT power_out Regulated voltage output (电压输出端). Delivers fixed 3.3 V ±2% up to 150 mA for the A33 variant. Requires a low-ESR ceramic output capacitor of ~20 uF for stability. Short-circuit current is typically 18 mA.

CAD (KiCad official)

  • Symbol: ME6228A33PG
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3 (KiCad packages3D, STEP)
  • 3D model files: me6228a33pg-etched.step / me6228a33pg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); me6228a33pg.step / me6228a33pg.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
me6228a33pg.step 57 KB You want the bare part, or you mark your own boards.
me6228a33pg-etched.step 1.8 MB You want the part with ME6228A33PG already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 462 faces against 42 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 (12 pp, sha256 4babba5a77f5a54d, 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).
