1. A regulator circuit, comprising:
a current detector configured to sense a load current and convert the sensed load current to a DC current sense signal; and an adjustment circuit comprising:
a logic circuit configured to input the DC current sense signal and generate an adjustment signal based on the DC current sense signal; anda digital-to-analog converter configured to input the adjustment signal and generate an output voltage control signal based on the adjustment signal, wherein the adjustment circuit is configured to adjust an output voltage within predetermined upper and lower voltage limits based on the DC current sense signal, and wherein the output voltage control signal causes the output voltage to increase or decrease within the predetermined upper and lower voltage limits.
