LTC3526L-2 quiescent current

Question

Hi, 
 I am using the boost regulator LTC3526LEDC-2 to have at the output 3.3V from AA 1.5V 1.2Ah battery. At no load condition I want to get a quiescent current lowest as possible, and I could have quiescent current reduction by increasing the feedback resistors. 
 My question is what is the upper limit of the feedback resistors ? 
 Thanks in advance.

I would say around an added total of around 10Meg ohm feedback resistors on the output will be enough here. If you go any higher, you may have problems with noise dominating the feedback node due to the high impedance node created by the large resistors. Also, finding resistors in general may be difficult if you go too high. Hope this helps!)
