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

How does the XC6901D541MR-G handle output discharge during standby?

When the CE pin is set to a low level, an internal P-channel MOSFET activates to quickly discharge the charge stored on the output capacitor, returning the -VOUT pin to the VSS level.

What is the function of the CE pin on this regulator?

The CE pin serves as an ON/OFF control input. A high-level signal activates the regulator, while a low-level or open signal places the device in standby mode.
