Thus my voltage changing function checks if regulator is enabled Ugh, this chip is not very good is it? Don't bounce the supply to change the voltage silently, that's clearly a bad idea - the devices using the supply are going to get very upset when the power gets removed just because they changed the voltage. Instead implement a custom set operation that returns an error if the user attempts to change the voltage while the regualtor is enabled.
