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

Does the XC6501C35B0R-G require an external output capacitor?

No, the device features internal phase compensation, allowing it to operate stably without an external load capacitor (CL).

What is the function of the CL auto-discharge feature in this model?

The CL auto-discharge feature rapidly discharges the electric charge stored in an external output capacitor when the CE pin is pulled low, quickly returning the VOUT pin to the VSS level.

How does the CE pin affect power consumption?

Inputting a low-level signal to the CE pin puts the circuit into standby mode, reducing the supply current from approximately 13μA to less than 0.1μA.
