Abstract
A system, a voltage regulator and a method for regulating power are disclosed, wherein the system may include a processor, a voltage regulator circuit, and a memory unit. The voltage regulator circuit may be configured to generate a first power supply voltage provided to the memory unit. The voltage regulator circuit may be further configured to adjust a voltage level of two output nodes dependent upon a level of the first power supply voltage and a level of a reference voltage. The voltage regulator circuit may be further configured to adjust the level of the first power supply signal dependent upon the level of at least one of the two output voltages. The voltage regulating circuit may also provide the first output voltage to the second output voltage via an impedance.
