Abstract
A voltage regulator circuit (100) for coupling to a power supply voltage (BPLUS) generates and regulates an output voltage (VREG). The voltage regulator circuit (100) includes a gain control element (148) for controlling the loop gain of the voltage regulator circuit (100) in response to the output current. Under heavy load conditions, the gain control element (148) functions to reduce (716) the output voltage (VREG) and thus the output current of the voltage regulator circuit (100) to avoid an overload that would pull the power supply voltage (BPLUS) below a predetermined level.
