Abstract
Apparatus and methods for reducing output load transients of a low dropout voltage regulator (“LDO”) are disclosed herein. A voltage regulator includes an output driver coupled to a regulator output pin, the output driver provides current to a load external to the regulator. A clamping device is coupled between the output pin and an internal node of the regulator. The clamping device forces a voltage at a control input of the output driver to follow the voltage at the output pin when the output driver is disabled.
