Abstract
A switching regulator for use with various kinds of electric and electronic equipment as a DC stabilizing power source. The switching regulator has a switching element implemented as an n-p-n switching transistor, an overcurrent detecting circuit for detecting an overcurrent ascribable to a fault, and a start delaying circuit for, after the switching transistor has been caused into an inactive state, feeding to the transistor a starting current which is delayed by a predetermined period of time. When the fault is removed, the switching transistor resumes its turn-on and turn-off operations immediately so as to restore the switching regulator to normal rapidly.
