For reference, TOKO has a series of LDO regs - advertised in
Digikey. Not especially cheap, but worth looking at.

I haven't sized this up for your app, but you might look at the idea
of using a 7660-type voltage converter chip in a voltage doubler
configuration. These chips are pretty cheap from Mouser.
