1. A power circuit comprising:
a plurality of regulators coupled to an external power voltage and configured to adjust a level of an input voltage to generate a plurality of internal power voltages, wherein timings when the plurality of internal power voltages generated by the plurality of regulators reach the target level are different; and
a plurality of in-rush current controllers configured to provide the input voltage to the plurality of regulators, the input voltage corresponding to an increasement voltage, the increasement voltage having a level rising at a preset rate until the plurality of internal power voltages all reach a target level.
