Hi
In LDO we can categorize its specifications under 3 main categories
Static specifications (like line/load regulation)
Dynamic specifications like transinet response)
High frequency specifications like PSRR and noise

Under what category of those we can add stability of LDO?

Best Regards,
Mahmoud
 

You can see the effects of loop stability in both "dynamic"
(overshoot / ringing / settling time) and "high frequency"
(oscillation, PSRR rolloff) categories.

So we cant categorize stability in general under certain category of the three mentioned
 

There is the time domain : frequency domain duality,
which would you rather ignore? And why?
