摘要： A constant voltage supplying circuit including an output transistor is connected to a power source line and an output terminal. A base-emitter voltage of the output transistor is detected by a voltage detecting circuit composed of a transistor. A current-outputting circuit for supplying a current determined based on the voltage detected by the voltage detector to a reference voltage supplying circuit is used in the constant voltage supplying circuit. The reference voltage is supplied to a base of the output transistor to cancel a base-emitter voltage of the output transistor and to equalize the output voltage to a voltage generated in a reference voltage generating element included in the reference voltage supplying circuit. In this manner, the output voltage is kept constant notwithstanding variation of output current.

摘要： In the high side switch type of electrical load driving circuit, wherein an N channel MOS transistor is provided on the circuit for supplying power to the electrical load, a zener diode is provided between the drain and the source of the MOS transistor to protect the MOS transistor. A load is provided between the gate and the ground to protect the MOS transistor. In this circuit, when a positive high voltage is induced on the side of the electrical load, the zener and a parasitic diode of the MOS transistor flows forward currents which absorb the high voltage noise. When a negative high voltage noise is induced from the side of the electrical load, a breakdown current flows through the zener diode, so that the voltage difference between the drain and source is clamed to a predetermined voltage. Then, the diode turns on the MOS transistor. Thus, the MOS transistor can be surely protected from high voltage noises without increasing the current capacities of elements for the protection circuit.

摘要： The present invention discloses an output circuit, by which it is possible to reduce power consumption while maintaining maximum voltage value to be outputted at high level. In this output circuit, a charge-and-discharge circuit uses a terminal voltage Vc of a capacitor as a trapezoidal wave voltage, and a drive circuit drives an output transistor based on the terminal voltage Vc, and a voltage Vo equal to the terminal voltage Vc is outputted to the load. A voltage detection circuit detects an emitter voltage (Vc+VF) of the transistor and generates an electric current proportional to the terminal voltage Vc. This electric current is turned to a base current of the output transistor via a variable current circuit. Therefore, a base current proportional to the output voltage Vo is supplied to the output transistor.
