    Hi JH,

    Did you have any design requirements for this design, such as transient response or efficiency?

    Are all the output caps that are shown installed, or are some placeholders?  We usually don't use tantalum caps, for example.  Why is that one used here?

    The EN pin must see at least 15k of resistance in series, between it and the driving source.  I do not see this resistance on the schematic.

    Thanks,

    Chris
