Abstract
A voltage regulator includes a comparator, a first voltage output unit, a second voltage output unit, a third voltage output unit, a first switch and a second switch. The voltage regulator receives an operating voltage and a reference voltage generated by a reference voltage generator, and then outputs a corresponding output voltage. The voltage regulator of the present invention can provide an operation mode, a suspend mode and a standby mode and can be switched among these modes to provide corresponding current driving capacity for respective operation states. When in the operation mode, the voltage regulator can supply a great current. When in the suspend mode, the voltage regulator consumes less power. When in the standby mode, the voltage regulator consumes even less power.
