A power conserving electronic circuit is provided having one or more main electronic devices or components powered by the output of a voltage regulator circuit. The voltage regulator is powered by a first power input, such as a battery. A real time clock circuit enables the voltage regulator, which, in turn, enables the main devices. The real time clock further provides an enable/disable output to a switch circuit whereby the real time clock circuit is powered by the output of the voltage regulator when the main devices are active and powered from the battery when the main devices are inactive.
