XC6220B331MR-G

Torex Semicon · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-25

XC6220B331MR-G from Torex Semicon, in a SOT-25. 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 VIN power_in Power input. Operating range 1.6V-6.0V (absolute max VSS-0.3 to +6.5V). Bypass with a ceramic capacitor (typ. 1 µF) close to the pin.
2 VSS power_in Ground reference for the regulator. Common return for VIN, VOUT, and CE.
3 CE input Chip Enable (ON/OFF control). VCE ≤ 0.4V = OFF (stand-by), 1.2V ≤ VCE ≤ 6.0V = ON. Absolute max VSS-0.3 to +6.5V. Do not leave open on A/B series (undefined); C/D series has internal pull-down.
4 NC unconnected No internal connection. Leave floating or tie to VSS.
5 VOUT power_out Regulated output, factory-trimmed to 3.3V (0.8V-5.0V range in family). Output current up to 1000mA (limit ~1200mA typ). Requires a low-ESR ceramic output capacitor CL (typ. 1 µF; 22 µF for inrush spec).

CAD (KiCad official)

  • Symbol: XC6220B331MR-G
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-25 (KiCad packages3D, STEP)
  • 3D model files: xc6220b331mr-g-etched.step / xc6220b331mr-g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); xc6220b331mr-g.step / xc6220b331mr-g.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
xc6220b331mr-g.step 85 KB You want the bare part, or you mark your own boards.
xc6220b331mr-g-etched.step 2.8 MB You want the part with XC6220B331MR-G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 675 faces against 102 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: Torex Semicon datasheet (31 pp, sha256 36c8215b268fff0c, 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).
