Hi team,

Could you review three schematics as below? Especially, could you review the input and output capacitors? There are concerns that capacitor value cosiderign DC-bias can't meet device recommendation. 

Designator Value Description PartNumber Manufacturer
C49, C114,  0.1 uF CAP CER 0.1UF 6.3V X5R 0402 04026D104KAT4A KYOCERA AVX
C51, C116,  10 uF CAP CER 10UF 10V X5R 0603 0603ZD106KAT2A KYOCERA AVX

    Hi, 

    It looks like these devices are configured per datasheet recommendations. However, input capacitors C49 and C114 are not within the 4.7uF - 1000uF range specified in the datasheet. This could affect load transient response and device stability. 

    BR,
