Abstract
A power regulation circuit includes at least a first regulator connected to a second regulator in series forming a first regulator pair and a third regulator connected to a fourth regulator in series forming a second regulator pair. The first regulator pair is connected in parallel with the second regulator pair. Each individual regulator is configured to separately regulate an input voltage to a predetermined regulated output voltage. The second regulator pair regulates the input voltage if a short condition occurs within the first regulator pair and the second and fourth regulators each regulate the input voltage if an open condition occurs within the first or third regulator respectively.
