    Hi all,

    I want to design a power regulator circuit which has sleep mode
    function using ams1117. How do I do? Or do anyone know other ICs which
    performs similar function but small footprint?

    If by "sleep mode" you simply mean to turn it off under control of
    some external signal, look at other regulator chips with shutdown
    pins. There are so many of them, and you offered so little about your
    requirements, that it's useless to make a suggestion about which may
    be good for your application. Look on the National Semiconductor,
    Analog Devices, Linear Technology, ON Semiconductor and Maxim websites
    for ideas--and there are plenty other manufacturers who make low
    dropout regulators with a shutdown feature.
