Abstract
A low dropout regulator that produces an output includes a comparison circuit, configured to compare a signal representative of the output and a reference signal to produce a comparison result. The low dropout regulator also includes a loop controller, coupled to the comparison circuit, configured to generate an output circuit control signal based at least in part on the comparison result. The low dropout regulator also includes an output circuit, comprising two or more output stages, configured to adjust a number of active output stages of the two or more output stages based on the output circuit control signal.
