Abstract
Aspects of a method and system for a linear regulator with high bandwidth, PSRR, and a wide range of output current are provided. A method for isolating voltages in a circuit may comprise applying a reference voltage to an isolation resistor based on a supply voltage. An internal voltage at a reference point may be determined based on the applied reference voltage, and a maximum and/or minimum voltage may be determined based on the internal voltage. A plurality of output transistor devices may be controlled based on either the maximum voltage or minimum voltage. The reference voltage may be modified based on controlling the plurality of output transistor devices. By turning ON and OFF the output transistor devices, a much wider operating range is facilitated.
