a) In the datasheet, Table 1 lists a cap 'C4' which I am assuming is mislabled on the schematic (Fig. 13) and is supposed to be across R1.
b) the value listed for a 3.3V output, this mystery cap is 10-47pf. However, if you look at the EVM doc in Table 3, this is shown as 680pf (yes, I know it's not populated, but still.....). On the EVM this is 'C2'.
