<p>PROBLEM TO BE SOLVED: To reduce current consumption at the time of light loads, to supply a sufficient operation current at the time of heavy loads and to secure sufficient load regulation. SOLUTION: Error signals obtained by comparing a voltage VR detected in an output voltage detection circuit 13 with a reference voltage V1 in an error amplification part 11b are inputted to an output control part composed of transistors Q1 and Q2 and an output voltage is controlled to a constant voltage corresponding to the reference voltage. When a load current increases, the operation current of the error amplification part is increased and the load regulation is secured.</p> |
