Input is battery -> PMOS reverse protection + cap.
Output is (currently) bypass capacitors per datasheet.

I'm not sure what the series cap for the input of the LDo would do.
It gives me input protection, but not protection against Vout<Vin,
which is the case when a programmer is powering the circuit and
the battery is disconnected.
