Abstract
This invention relates to a quick-recovery low dropout linear regulator (LDO), which utilizes a current-detection circuit to detect the magnitude of the output current, and the output current compares with a reference current so as to dynamically adjust the bias-current of the 2nd stage amplifier such that the system remains stable even when the output current is high resulting from the damping ratio ζ is still greater than 1. As a result, the output voltage can quickly recover stability from a large and sudden change of the output current.
