I would like to know if there is a maximum limit to the bypass capacitor (CFF).
In my simulator it also plays a role in the output impedance (low frequencies), I came up to 47µF !
The LT3015 Data sheet says : CFF ≥ 10 nF/100µA • IFB-DIVIDER
IFB-DIVIDER = VOUT/(R1+R2)
In my case IFB-DIVIDER = 14V5/(1.8k+19.6k) = 0,68 mA
CFF ≥ 68 nF
Is 47µF far too much ?
Should I limit this capacitor to 100 nF ?
What about the LT1963a, can I do the same ?
