I was planning on using the TI TPS62237 regulator to supply 3.3V from a LiPo battery, but I just noticed on the data sheet on page 3 "Recommended Operating Conditions" that minimum supply voltage should be Vout + 1V which would mean my battery should be 4.3V which is higher than a fully charged LiPo battery.  Am I reading that correctly?  I linked to the datasheet below.

Yes you are.


Boo!  Oh well.  What about something like this:

Yes, one is a buck, the other is a boost, regulator.

Thanks!  I will use that one instead.  Probably easier to solder as well.
