MG6208T3B-33

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

MG6208T3B-33 from Megain, 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 VOUT power_out Regulated output voltage pin. Delivers 3.3V (fixed for -33 suffix) at up to 150mA. Requires a >=1uF ceramic capacitor to GND; low ESR ceramics acceptable. Output tolerance +/-2% over temperature.
2 GND power_in Device ground reference. Common return for input and output bypass capacitors.
3 VIN power_in Unregulated input supply pin. Operating range 5V to 24V (absolute max 25V). Requires a >=1uF bypass capacitor to GND. Dropout is 650mV at 100mA, 1100mV at 150mA.

CAD (KiCad official)

  • Symbol: MG6208T3B-33
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: mg6208t3b-33-etched.step / mg6208t3b-33-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mg6208t3b-33.step / mg6208t3b-33.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
mg6208t3b-33.step 59 KB You want the bare part, or you mark your own boards.
mg6208t3b-33-etched.step 2.6 MB You want the part with MG6208T3B-33 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 609 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 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.
