Abstract
A low dropout voltage regulator with switching output current boost circuit. In one aspect of the invention, a voltage regulator circuit includes a low dropout voltage regulator providing an output voltage at an output based on an input voltage at an input, and a boost circuit connected to the low dropout voltage regulator. The boost circuit includes a comparator and a boost transistor device for allowing additional current to be provided to the output of the low dropout voltage regulator when the output voltage of the current regulator falls below a predetermined threshold.
