A voltage regulator circuit includes a first voltage regulator having a first output voltage selection pin set and producing a first output voltage based on a first digital signal received at the first output voltage selection pin set, and a second voltage regulator having a second output voltage selection pin set and producing a second output voltage based on a second digital signal received at the second output voltage selection pin set. The first and second voltage regulators are operable in a voltage tracking mode with the output voltage of the second voltage regulator tracking the output voltage of the first voltage regulator when digital signals received at the selection pin sets have a same value. An overvoltage sensor detects overvoltage events at the first voltage regulator. Control circuitry selectively avoids operation in voltage tracking mode as a result of an overvoltage event detected at the first voltage regulator.
