Hello Danilo,

There's no switching that occurs in this LDO.

Hi Aaron,

Thank you for your quick response. In the datasheet, there are several graphs that shows the parameters of the device versus the frequency, for example output impedance vs frequency, output noise versus frequency and etc. Is this frequency related to the frequency from other devices in the customer's circuit board?

Regards,

Danilo

Yes, those are from an external source, the LDO is not creating any switching internally.
