TM4C1290NCPDT: Use 4.7uF capacitor instead of 3.3uF on LDO capacitor?

Part Number: TM4C1290NCPDT

Hi,

DATA SHEET of TM4C123A/1290 said 2.5uF-4.0uF capacitor is required for LDO.

So my customer used 3.3uF, but capacitor makers are discontinue.

Can they work correctly on 4.7uF capacitor instead of 3.3uF?

The reason of this question is capacitor maker continues supplying 4.7uF capacitors and pin-to-pin compatible capacitors.

  

Also, Capacitor has the frequency-characterization. Does TM4C require 2.5uF-4.0uF capacitors on DC component only?   How frequency range is required on 2.5uF-4.0uF capacitors?

 

My customer is urgently re-making the board.   Please advise me.

 

Thanks and best regards,

M.HATTORI.
