Abstract: An electronic circuit includes parallel linear regulator circuits that support a range of different load currents. The electronic circuit includes a first linear regulator circuit coupled to an output node, a second linear regulator circuit coupled in parallel with the first linear regulator circuit and the output node, and a control circuit. The control circuit is configured to monitor the output node and to suppress or inhibit the second linear regulator circuit from supplying the output node when a representation of load power consumption is below a specified threshold. The first linear regulator circuit is configured to continue to supply a portion of the load power when the representation of load power consumption is above the specified threshold, and the control circuit may disable the second linear regulator circuit when the representation of load power consumption is below the specified threshold.
