Abstract
A triggered sink circuit for a linear voltage regulator, such as low-dropout voltage regulator (LDO), is disclosed. The triggered sink circuit is activated only when needed to sink current from an output in response to a transient load change. The triggered sink circuit includes a large sink transistor that when activated drains current from the output of the LDO to quickly restore an output voltage back towards a regulated value, thereby improving a load transient response to the load change. The improved load transient response prevents the output transistor of the LDO from being completely deactivated to restore regulation. Accordingly, the LDO's response to a subsequent load transient can be improved.
