    Hi Grieshma,

    Could you please confirm that the COUT is 0806 package or not? We recommend to use 3 pcs 0805 22uF/10V capacitors at VOUT, the effective capacitance of COUT is smaller if w/ smaller package size capacitor.

    Also, we recommend to add a placeholder of feedforward capacitor and resistor between COUT and FB as below, for potential load transient improvement if needed. 50ohm + 10pF is an usual setup for most cases.

    Regards,

    Nathan
