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

Does the XC6221A142MR-G include an internal auto-discharge switch?

No, the 'A' designation indicates the absence of both a CE pull-down resistor and a CL auto-discharge switch.

What is the logic level requirement for the CE pin?

The CE pin is active high; a high-level signal turns the regulator on, while a low-level signal activates the stand-by mode.
