I agree with you that the main objectives between both circuits are different - specially for a low quiescent & LDO regulator battery-powered. For non-battery operated circuits, richer in AC and HF switching noise, if -60dB is not enough with the regulator alone, I understand from you that it would be ok to add a CapMult as Ripple Smoother, with the ‘penalty’ of 1~2V for additional dropout. Ironically, this increased voltage drop would demand higher input capacitance to minimize voltage minimums and avoid loss of voltage regulation. | |
