    Hi Shyam,

    You don't need 3 input caps in parallel you will be fine with just 1, 10 uF capacitor. The rest of the schematic looks good. As far as the board layout, can you attach the GND pin on the bottom right to the GND plane instead of just through a trace? This would allow for better thermal dissipation. 

    Thank you,

    Josh Nachassi
