Abstract: PURPOSE: To fix the starting current of a regulator and to reduce power consumption. CONSTITUTION: When the regulator is not operated, the voltage of a terminal 6 connected to the start terminal of the regulator is low, a transistor Q8 is turned off, and a transistor Q7 is turned on. Thus, the base potential of a transistor Q6 is turned to a ground potential, transistors Q6 and Q5 are turned off, and a current mirror operation is stopped. Therefore, no collector current flows to a transistor Q4 and a transistor Q3 is turned off. As a result, transistors Q1 and Q2 are operated as a current mirror circuit, a constant current decided by a constant current circuit I1 is supplied from the collector of the transistor Q1 through the terminal 6, and the regulator is started. Besides, when the transistors Q3, Q7 and Q8 are turned on, only the fixed current flows to those transistors and that current is not increased even when a power supply voltage is high.
