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

How does the XC6901D33BMR-G handle output discharge during stand-by?

When the CE pin receives a low-level signal, an internal P-channel MOSFET and discharge resistance activate to quickly discharge the output capacitor, returning the -VOUT pin to the VSS level.

What protection mechanisms are included in this regulator?

The device includes a fold-back current limit circuit to protect against short circuits and excessive load currents, as well as a thermal shutdown circuit that activates if the junction temperature exceeds the limit.
