LP2950-N: LP2950CDTX-3.3/NOPB issue

Part Number: LP2950-N

Hi team,

My customer is using LP2950CDTX-3.3/NOPB to covert 12V to 3.3V in their project, but they failed the radiation spurious test in the FCC certification test of BT.

The reason for asking us about this question is because the customer said that if it is directly powered by a 3.3V battery, it can pass the test, but it will fail if it uses LP2950CDTX-3.3/NOPB.

This is the schematic, could you please help review it and give some comments?

Appreciate your help!
