Abstract

Battery powered systems have current drain as a critical parameter. Battery life is a parameter that directly effects and is noticed by the end user. Smaller and smaller end product packaging means fewer battery cells and therefore lower system voltages, making the ability of circuits to operate at low voltage important. A function needed by many systems is a bandgap reference that can supply modest load currents, draw little supply current, have reasonable supply rejection, and have a low drop out voltage.
