Abstract

PURPOSE: To enable to reduce the effect of noise produced at one load circuit on other load circuits, by using the noise limiter the same as the output impedance of the reference voltage generating circuit or more.
CONSTITUTION: If the load circuit 2A is operated, noise is generated and if the load circuit 2B is operated after the noise is not decreased, the noise is fed to the load circuit 2B via the path of arrow. Since the noise limiter 4A has equal or more the impedance Z2 as the output impedance Z1 of the reference voltage generating circuit 1, the noise voltage appeared at the output node 5 of the reference voltage generating circuit 1 is smaller than a half the noise produced at the node 6A. Accordingly, if the reference voltage of the reference voltage generating circuit 1 is always constant, the propagation of noise caused at the node 6A to the node 6B or 6C is not almost arisen to prevent the malfunction of the load circuits 2B and 2C.
