Hello,

I am desiging a pre-regulator for the the LDO regulator( for digital ICs power supply ) to reduce the power supply noise.
In the pre-regulator, I need some load information to dynamicly adjust the bandwidth of the error amplify.
The problem now is how to generate such kind of replica load information since the exact load is unknow ?
I searched in web, there is no such kind information.

thank you for your answering,


regards,
