Abstract
A circuit includes a comparator that monitors a transient with respect to a predetermined threshold at the output of a voltage regulator and generates a compensation signal if the transient exceeds the predetermined threshold. A dynamic current pull-down block is triggered from the compensation signal of the comparator and operative with an output stage of the voltage regulator to mitigate the transient at the output of the voltage regulator by concurrently activating a plurality of current pull-down switches during the transient and sequentially deactivating each current pull-down switch of the plurality of current pull-down switches after its predetermined deactivation delay for each current pull-down switch.
