Abstract
Disclosed are a series regulator and electronic equipment. The series regulator includes a first amplifier that drives a first transistor connected between a power supply and a load, a second amplifier that drives a second transistor connected in parallel to the first transistor, an amplifier control circuit that controls whether or not operation of the first amplifier is possible according to the load, and a first overcurrent protection circuit that limits a first output current flowing in the first transistor to a first overcurrent set value or smaller. The first overcurrent protection circuit carries out variable control of the first overcurrent set value according to a second output current flowing in the second transistor. The electronic equipment includes the series regulator and a load that receives power supply from the series regulator and operates.
