ABSTRACT:
A multimode voltage regulator includes a low current pass device and a high current pass device each adapted for connection between a power supply and a load; an error amplifier responsive to a difference between a reference voltage and a function of the voltage on the load to produce an error signal; and a low power driver responsive in a low load power mode to an error signal for operating the low current pass device to provide low power to the load and a high power driver responsive in a high load power mode to an error signal for operating the high current pass device to provide high power to the load for maintaining efficiency over high and low power load operation.
