LDO output capacitor
Hi All,
Needed some info on output capacitor for LDO .Based on stability requirements ,one can have the output cap from 1uF to 3uF based on the dominant pole location & scale the ESR accordigly so as to have the loop stability .My question is how to choose the value of the cap ? What is the ratio between Ropass and Resr ?
Any help would be appreciated .
