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

How does the auto-discharge function operate in the XC6222C14BPR-G?

When a low-level signal is applied to the CE pin, an internal N-channel transistor connects the output capacitor to the VSS pin, allowing the stored electric charge to discharge rapidly and pulling the VOUT pin to the VSS level.

What protection circuits are integrated into this regulator?

The device integrates over-current protection, which limits the output current, and thermal shutdown protection, which turns off the driver transistor if the junction temperature exceeds the limit.
