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

How does the XC6222C25BPR-G handle output discharge during shutdown?

The XC6222C type does not feature an internal auto-discharge switch for the output capacitor. When the CE pin is pulled low, the output voltage returns to the VSS level through internal resistors R1 and R2, resulting in a slower discharge time compared to B, D, F, or H types.

What is the recommended output capacitor value for this regulator?

For the 2.5V output version, a ceramic output capacitor (CL) of 2.2μF or higher is required for phase compensation and stable operation.
