Abstract
A voltage regulator circuit is provided in which voltage overshoots are quickly dissipated using a discharge path which is connected to an output of the voltage regulator. Circuitry for controlling the discharge path is provided using internal currents of an error amplifier to provide a space-efficient and power-efficient design with a fast response. Moreover, hysteresis can be provided to avoid toggling between discharge and no discharge, and to avoid undershoot when discharging the output. A digital or analog signal is set which turns the discharge transistor on or off. A current pulldown may be arranged in the discharge path.
