TS3USBA225: Asking for the TS3USB225 decoupling cap design

Part Number: TS3USBA225

Hi Team,

Customer would like to check whether they can use 1uF on the VCC side to replace the 10uF cap.

Please provide your comment.

BR,

    SHH,

    Reducing your bulk capacitance will leave the IC vulnerable to potential low frequency VCC dips/noise on VCC. If the power supply noise to the IC is low then reducing this capacitance is okay but we do recommend 10 uf for bulk capacitance for this device.
