I am creating a mixed signal PCB which has two separate supplies: A buck converter for the digital section and an LDO Regulator for the analog one.

Each regulator steps down 5V from a USBc supply to 3.3V. 
The digital section draws up to 3A, while the analog section draws up to 500mA.

For the digital side, I am using a TPSM82864AA0SRDJR Buck Converter (lower regulator on the picture, 2.4 MHz switching frequency) and for the analog section, an AMS1117-3.3V, both powered by the VBUS supply line (USBc, see schematic on the top left).

I  have placed a Pi filter consisting of two 1uF capacitors and a ferrite bead (capable of handling the needed current) in order to supress the high frequency noise from the (usually very noisy) USBc supply rail before reaching my voltage regulators.

I want to ask if this Pi filter arrangement is a good idea considered my regulator setup, or if a different approach would be more appropriate.

Thank you very much in advance.
