ABSTRACT:
A method and apparatus to dynamically modify the internal compensation of a low drop-out (LDO) voltage regulator is presented. The process involves creating an additional equivalent series resistance (ESR) from an internal circuit. The additional ESR of the internal circuit is sufficient to ensure the DC output stability. This allows the ESR of the output capacitance to be reduced to zero if desired, for improved transient response.
