Filed: 1984-06-28
Abstract: PURPOSE:To obtain a reference voltage which has excellent output rising characteristics at the time of making power supply and a low percentage ripple, by separately charging the capacity of the input terminal of a voltage follower at a current path provided between the input terminal and a power source terminal under a transient state of supplying an electric current. CONSTITUTION:A reference voltage terminal 31 is connected with the input terminal 5 of a voltage follower 4 through a low-pass filter composed of a resistance R and capacity C and bases of transistors Q1 and Q2 of a differential amplifier circuit 6 are respectively connected with a bias output terminal 32 and the input terminal 5. Moreover, the input terminal 5 forms a current path through a transistor Q3 between said terminal 5 and a power source terminal 1, and the traisistor Q3 and another transistor Q4 connected to the collector side of the transistor Q1 of the circuit 6 constitute a mirror circuit. When the power supply is turned on, the voltage at the input terminal of the voltage follower gradually rises from zero, since the time constant of the low-pass filter is large. At this time, the transistor Q3 for switching current of the current path between the power source terminal and input terminal of voltage follower is turned on by the current flowing through the transistor Q1 and the capacity of the low-pass filter is quickly charged by the electric current flowing through the transistor Q3.
