I am currently designing a LDO voltage regulator. It is well known that the ESR of the compensating capacitor contributes a zero to stabilize the system. Right now, I have a problem, i.e. I do not know what is the ESR value of a ceramic capacitor. I cannot find any information on ESR value of a ceramic capacitor. Could someone please tell me what is the typical value of the ESR of a ceramic capacitor?
I also notice that some LDO voltage regulator sold by TI are guaranteed to be stable with any capacitor regardless of the ESR value. Any circuits techniques to achieve this? Thanks.
