17. A method, comprising:
receiving a first external power voltage
receiving a second external power voltage
reducing the first external power voltage by a first amount to provide a first internal power voltage at a first internal power node;
reducing the first external power voltage by a second amount to provide a second internal power voltage at a second internal power node, the first amount greater than the second amount; and
providing the second external power voltage to the second internal power node when the second external power voltage reaches a trigger voltage level.
