TPS51285A: TPS51285A ----- Output capacitor of VREG3 and VREG5

Part Number:TPS51285A

Hi ,

According to TPS51285A datasheet suggestion , a ceramic capacitor with a value of 4.7 µF or larger (X5R grade or better) is required for each of VREG5 and VREG3.

If I change the capacitor value from 4.7uF to 1uF, will the controller  have abnormal fucntion? Is it a critical issue to do this change?

 I measured  VREG3 voltage level is stable in 3.3V even though the capacitor with 1uF.

Sincerely,

Chin
