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

How does the XC6227C221ER-G handle reverse current flow?

The device includes a reverse current protection circuit that prohibits current flow from the VOUT pin to the VIN pin when the output voltage is higher than the input voltage.

What is the function of the CE pin on this regulator?

The CE (Chip Enable) pin allows the entire internal circuitry to be placed in a stand-by state when a low-level signal is applied, significantly reducing power consumption.
