That's what switched capacitor regulators are for (like the 
TPS60240).  Generally low current but it looks like that is something you 
are watching anyway.

Well considering the 2103 claims a typical operating current on the 1V8 
supply of from 7mA to 41mA you are already in a different league.  Three 
orders of magnitude is not easily crossed.
