ME6228A50PG

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

ME6228A50PG 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 / negative supply reference (地). Common return for input and output currents; connect directly to the system ground plane.
2 VIN power_in Power supply input (电源输入端). Accepts 5.0V to 30V (absolute max 30V). Recommended input capacitor CIN = 10µF; when VIN > 15V an electrolytic or tantalum input cap is required due to ceramic-cap inrush spiking.
3 VOUT power_out Regulated voltage output (电压输出端). Fixed 5.0V ±2% for the A50 option; delivers up to 150mA (typ) with 18mA typical short-circuit current limit. Requires low-ESR ceramic output capacitor (COUT = 20µF recommended).

Two STEP files. Same geometry, different body top:

File Size Use it when
me6228a50pg.step 57 KB You want the bare part, or you mark your own boards.
me6228a50pg-etched.step 1.8 MB You want the part with ME6228A50PG already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 452 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)
  • 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).
