Abstract: In an example, a device includes a controller and a direct current (DC)-to-DC converter coupled to the controller and configured to provide a load current to a load. The device also includes a low-dropout (LDO) regulator coupled to the DC-to-DC converter. The controller includes digital logic, and the digital logic is configured to determine the load current. The digital logic is configured to turn on the LDO regulator if the load current is above a predetermined threshold. The digital logic is also configured to turn off the LDO regulator if the load current is below the predetermined threshold.
