A circuit for optimizing a power management system. The circuit includes a first amplifier. The first amplifier is responsive to a first reference signal and operable to supply a first load current. The circuit also includes a second amplifier coupled to the first amplifier. The second amplifier is responsive to a second reference signal and operable to supply a second load current. The second load current is lower in magnitude than the first load current, thereby enabling the first amplifier to operate during a first load condition, and the second amplifier to operate during the first load condition and a second load condition. Further, the circuit includes a resistive element coupled to the first amplifier and the second amplifier, to isolate the first amplifier from the second amplifier.
