Abstract
An integrated circuit device has a primary voltage regulator and an ultra-low power secondary voltage regulator. The ultra-low power secondary voltage regulator supplies voltage to certain circuits used for providing data retention and dynamic operation, e.g., a real time clock and calendar (RTCC) when the integrated circuit device is in a low power sleep mode. The primary voltage regulator provides power to these same certain circuits when the integrated circuit is in an operational mode.
