1. An electric device, comprising:
a secondary battery; and a power supply circuit for dropping an input voltage which is input from the secondary battery to an output voltage and outputting the output voltage to a load, wherein the power supply circuit drops the output voltage when the input voltage falls below a predetermined first threshold value from the output voltage output when the input voltage is equal to or higher than the predetermined first threshold value; and wherein, when the input voltage transits from a state of being equal to or higher than the predetermined first threshold value to a state of being lower than the predetermined first threshold value, the power supply circuit waits until the state in which the input voltage is lower than the predetermined first threshold value continues for a predetermined first time period and then drops the output voltage. |
