ABSTRACT:
A power supply circuit is provided with a supplemental power source which is intermittently brought into service each time a main power source is coupled to a high power drain circuit. That is, the supplemental power source is switched to a circuit, which is susceptible to power drop, in response to switching over of the main power source to the high power drain circuit.
