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

What is the recommended output capacitor value for the XC6222A21BMR-G?

For an output voltage between 2.1V and 2.45V, a ceramic output capacitor (CL) of 4.7μF or higher is required for phase compensation.

How does the B-type designation affect the CE pin behavior?

The B-type designation indicates the absence of a pull-down resistor on the CE pin but includes an internal auto-discharge switch for the output capacitor when the CE pin is low.
