ABSTRACT:
An automotive voltage regulator circuit for supplying a predetermined voltage to first and second optically connected and electrically separated digital electronic circuits includes first and second serially connected voltage regulators. The total drop-off voltage is reduced and the total current consumption is smaller for the two serially connected regulators as compared with two parallel circuits. Consequently, the total power consumption is reduced.
