Abstract
A level regulator for an automotive vehicle such that a power voltage is applied to the amplifiers only for a fixed period after a level signal has been detected or only while a level signal is being detected within a fixed period, so that a wasteful current can be prevented from being passed therethrough when the vehicle is left parked with one of the wheels on the sidewalk or uneven ground, and the battery can be protected against excessive discharge. The level regulator of the present invention comprises a power supply controller including a differential circuit, a switching transistor and a timer of a monostable multivibrator.
