I have a postage stamp sized module that takes 2.4V to 5.5V in and
outputs 3.3V at up to 150mA. It has self healing fuse, reverse polarity
protection, and a shutdown pin if you're interested. I have a similar
module that takes 0.7V to 5.5V in and can output up to 1A at 3.3V. The
second board can be modified for 3V out. How you tie it into the clock
depends upon which clock you are using. Other than that there are plenty
of build it yourself options that I know of.
