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

How does the XC6222C13BMR-G handle output capacitor discharge?

Unlike D-type variants, the C-type does not feature an internal auto-discharge switch for the output capacitor. Discharge relies on external resistive paths or load conditions when the CE pin is pulled low.

What is the minimum recommended output capacitance for this device?

For an output voltage of 1.3V, which falls within the 0.8V to 2.05V range, a minimum output capacitance (CL) of 6.8μF is required for stable phase compensation.
