Abstract: A regulator circuit included in a computer system may include a control circuit and multiple pass circuits that source respective supply currents to a regulated power supply node by adjusting respective conductance values between an input power supply node and the regulated power supply node. The number of pass circuits can be adjusted on a design-by-design basis based on a threshold load current for the regulator circuit or on a threshold conductance between the input power supply node and the regulated power supply node. The control circuit adjusts the respective conductance values using a combination of respective sense currents generated by the multiple pass circuits along with a reference voltage and a voltage level of the regulated power supply node.
