An apparatus, system, and method for voltage regulator (VR) control are provided. An apparatus can include first, second, and third comparators configured to determine whether a load voltage (VLOAD) drops below a lower non-linear control (NLC) threshold, drops below a lower linear control (LC) threshold, and exceeds an upper LC threshold, respectively. The apparatus can include power gates (PGs) configured to adjust an output voltage (VOUT) based on a provided power gate (PG) code. The apparatus can include voltage regulator (VR) controller circuitry comprising synchronous LC circuitry and asynchronous NLC circuitry, the LC circuitry configured to increment or decrement the PG code responsive to the VLOAD dropping below the LC threshold and exceeding the upper LC threshold, respectively, and the NLC circuitry configured to increase the PG code based on a number of consecutive NLC droop events and responsive to the VLOAD dropping below the lower NLC threshold.
