Abstract
Provided is a voltage regulator having low current consumption, which is capable of preventing a reverse current from flowing thereto from an output terminal (), irrespective of a magnitude of a voltage of a VDD terminal (). The voltage regulator has a circuit configuration in which voltage dividing resistors are not used for a comparator circuit for comparing the voltage of the VDD terminal () with a voltage of the output terminal (), to thereby achieve lower current consumption.
