    Is there any IC that can output a precision 5V from a 5V supply?

    No I do not think so. What are you trying to make? can you tell us, as it would help us to help you ;)

    Doubt it, unless I have misunderstood what you want to do.

    There are several voltage regulators that will do precision 5V, but being voltage regulators you will need to input around 8V so they can bring it down in a precision sort of way.

    I remember your other thread, Precision 5V reference.

    It is possible to boost a 5V power supply several different ways and then regulate it down, but it would have low current capacity.

    As has been asked, what are you trying to do?

    Have a look at the Analog Devices REF195. If your 5V supply can be made to be 5.2V you will have an almost perfect 5V reference.
