Definitions
- One input terminal of the error amplifier circuit 6 is connected to the output terminal of the reference electrostatic pressure generation circuit 5, the other input terminal of the error amplifier circuit 6 is connected to a connection point of the resistor R, a resistor R 2, the error amplifier circuit the output terminal of the 6 Bok Rungis evening Q 2 total
- the transistors Q 42 and the transistor Q 41 is turned on when the level of the control signal applied to the control input terminal 3 becomes high. Then, through the transistor Q 41 of the power supply circuit 4b, the reference voltage generating circuit 5 connected to an external power source to the input terminal 1, the driving voltage is supplied to the internal circuits of the error amplifier circuit 6.
- the semiconductor device having the control input terminal 3 and having a configuration capable of turning on and off the operation from the outside is shown.
- one end of the resistor R 4 is connected to the control input terminal 3.
- the semiconductor device may be connected to the input terminal 1 so that the operation cannot be turned on and off externally.
- omitted diode D 4 2 power supply circuit 4 in a such as a reference voltage generating circuit 5 to the other circuit configuration, it is possible to change the circuit configuration within the range not changing the gist of the present invention .
