Abstract:
The invention relates to a regulator with a reference generator circuit (e.g., a band-gap reference) and a reference generator power selector. The reference generator power selector selectively powers the reference generator circuit from an input power signal during start-up and from a regulated power signal during steady-state operation. The reference generator power selector may also select from multiple regulated power signals during steady-state operation.
