I see that recommend lower resistor value for 3.3V output is 324kohms (with upper resistor @ 1.02Mohm referencing table 3 of the datasheet). That works out to ~ 2.5uA in the resistor divider chain (if there were no IFB leakage).
The leakage spec for the part is 0.02uA typical but can be as large as 1uA over temperature. Wouldn't this introduce a large error in the output voltage when using a 1.02M upper divider resistor?
Please reconcile this so that a circuit may be designed to maintain 3.3V output over temperature. If were to limit the impact of the 1uA leakage to say, a 33mV impact on the output voltage, then we'd have to use something like 33Kohms for the top resistor and 10.4K on the bottom. This is way outside the recommended resistor values (~ 10X less) - is that ok?. What output capacitance would be required in that case? 5uF? 10uF? How would we determine this?
