Our customer is using TPS78033022 to provide power to CC2652, TPS78033022 demand at least 1uF capacitor. If the customer wants to design the below circuit, whether it will influence TPS780 output?

This would likely be unstable. I recommend adding a 1uF capacitor between the TPS780 and the Ferrite bead.
By the way, have you seen the TPS7A02? This is a much lower IQ and has better all-around performance LDO. The SOT-23 package will RTM in Dec. 2019 and the other packages later next year.
Let me know if this answers your question.
