    Is it required any load to get the output supply supply the above configuration is for 12V  fixed output. And the input supply is 12V

    Hello Ashish,

    You do not need to have load current to get a regulated output voltage. 

    I recommend comparing your schematic with the standard application in the datasheet as this is a good reference for the necessary external components.

    In general the schematic seem to be ok, but I did not re-calculate all external components.

    A good advice for a prototype is to have the capability to change external components easily for different IC features if testing shows that these are necessary. So having spare footprints for certain features like PS to high or so, might be helpful for debugging.

    Best regards,
    Brigitte
