ABSTRACT:
The voltage regulator of the boosting/lowering type is comprised of a switching regulator block and a series regulator block, which are cascade-connected to each other. One input terminal of an error amplifier of the switching regulator block is connected to a dividing node of bleeder resistors in the series regulator block to constitute a regulative feedback loop effective to improve an efficiency of the voltage regulator.
