XC6221A332MR-G

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

XC6221A332MR-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 pin. Operating range 1.6V to 6.0V; absolute maximum VSS-0.3V to +6.5V. A 1.0µF ceramic bypass capacitor is recommended close to the pin.
2 VSS power_in Ground reference for the regulator and CE logic threshold.
3 CE input Chip Enable (ON/OFF control). Active HIGH: VCE >= 1.2V (typ up to 6.0V) turns the regulator ON; VCE <= 0.3V turns it OFF (standby, IDD < 0.1µA). XC6221A has no internal CE pull-down, so an open/floating CE is an undefined state and must be driven externally.
4 NC unconnected No internal connection. Can be left floating or tied to VSS for board-layout convenience.
5 VOUT power_out Regulated output pin, 3.3V nominal, ±2% accuracy, up to 250mA (typ). Requires a 1.0µF ceramic stabilization capacitor to VSS.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
xc6221a332mr-g.step 85 KB You want the bare part, or you mark your own boards.
xc6221a332mr-g-etched.step 2.6 MB You want the part with XC6221A332MR-G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 636 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 (28 pp, sha256 c5bad2e786b1d143, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
