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.
