CJ6211A33M

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

CJ6211A33M from Changjing, in a SOT-23-3L. 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 for the regulator. All output/input voltages are referenced to this pin.
2 VOUT power_out Regulated output voltage pin. Fixed 3.3V (A33 suffix) at up to 500-700 mA. Requires a 1µF ceramic COUT for stability; a low-ESR ceramic is recommended.
3 VIN power_in Unregulated power input pin. Operating range 1.8V to 6.0V (absolute max 7V). Requires a 1µF ceramic CIN close to the pin.

CAD (KiCad official)

  • Symbol: CJ6211A33M
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3L (KiCad packages3D, STEP)
  • 3D model files: cj6211a33m-etched.step / cj6211a33m-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cj6211a33m.step / cj6211a33m.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Changjing datasheet (11 pp, sha256 805289572b9842e1, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
