Abstract
A constant voltage circuit adapted for connection between high voltage power source and low voltage power source terminals respectively to output a constant voltage signal from an output terminal in response to a control signal inputted to an input terminal. The circuit has a resistor circuit including a MOS transistor for connection to the high voltage power source and activated in response to the control signal. A current mirror section is connected between the resistor circuit and the low voltage power source terminal to generate an output voltage to be outputted from the output terminal. A feedback section is connected between the resistor circuit and the low voltage power source terminal to control the current mirror section to keep the output voltage constant by detecting deviation of the output voltage.
