    Hi Ashish,

    The equivalent Cout required for stability is 10uF. After accounting for derating due to DC Bias and tolerance, please make sure a 22uF capacitor of 5V or higher rating is used in X5R or X7R types.

    Please make sure the current draw of both LDOs does not cause junction temperature to rise above 125°C. Follow the procedure described in section 11.3 of the datasheet.

    Regards
