In an example, a method includes enabling a first voltage supply and a second voltage supply. The method also includes selecting, with a decision comparator, a selected voltage supply from either the first voltage supply or the second voltage supply based on which of the first voltage supply or the second voltage supply ramps up first. The method includes monitoring the selected voltage supply with the decision comparator. The method also includes, responsive to a voltage from the selected voltage supply dropping below a dropout voltage level of a low dropout regulator, switching to an other voltage supply with the decision comparator.
