Single LM111 comparator is basis for simple overvoltage protection of circuits drawing less than 50mA. Fraction of input supply is compared to 1.2-V reference. When input exceeds reference level, power is removed from output.-R. C. Dobkin, Comparators Can Do More than Just Compare, EDN Magazine, Nov. 1, 1972, p 34-37.
