Abstract
A constant voltage generation circuit in which a charging circuit (T1) connected to one side of resistors (LR2 to LR5) rapidly supplies a higher voltage, that is further higher than any voltage generated at each of the resistors (LR2 to LR5), to the output terminal (OT) during a desired time period when one of switches (SW2 to SW4) turns on to provide the voltage to be switched to the output terminal (OT) and when the voltage to be switched is higher than a current voltage of the output terminal (OT). Furthermore, in the circuit, a charging circuit (T2 ) connected to other side of resistors (LR2 to LR5) rapidly supplies a lower voltage, that is further lower than any voltage generated at each of the resistors (LR2 to LR5), to the output terminal (OT) during a desired time period when one of switches (SW2 to SW4) turns on to provide the voltage to be switched to the output terminal (OT) and when the voltage to be switched is lower than a current voltage of the output terminal (OT).
