[sdiy] Really Small Linear Power Supplies ?

Also take a look at Maxim and Linear Tech's parts.
We use small switcher IC's in USB/firewire bridges at work to make efficient 
cool running regulator circuits but do not need negative voltages...  The 
link above gives you something to start with though. Lots of others doing 
the same thing.
