Abstract:
1. A voltage regulator, comprising: a first analog to digital converter generating a first digital stream according to the first output voltage and a reference voltage, and generating first data according to the generated first digital stream; a second analog to digital converter generating a second digital stream according to the second output voltage and the reference voltage, and generating the second data according to the generated second digital stream; a voltage adjustment device applying a predetermined weighting to the first data and the second data according to a power providing priority of a first load and a second load, and generating voltage control signals according to the weighted first data and the weighted second data to make the first output voltage reach a target voltage faster than the second output voltage according to the power providing priority; and a switching module respectively providing the first output voltage and the second output voltage to the first load and the second load according to the voltage control signals.
