Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

What is the function of the CE pin in the XC6223N3419R-G?

The CE pin controls the ON/OFF state of the regulator. A high-level signal activates the output, while a low-level signal shuts down the IC. This variant includes an internal pull-down resistor on the CE pin.

Does the XC6223N3419R-G have inrush current protection?

Yes, the 'N' designator indicates that this specific model includes a built-in inrush current protection circuit to limit surge currents during startup.
