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

What is the function of the CE pin in the XC6227C281ER-G?

The CE pin enables or disables the entire circuit. A high-level signal activates the regulator, while a low-level signal places it in a stand-by state.

How does the reverse current protection work?

It prohibits reverse current flow from the VOUT pin to the VIN pin when the output voltage is higher than the input voltage, protecting against battery current backflow.
