Abstract
For example, a linear power supply includes an output transistor connected between an input terminal of an input voltage and an output terminal of an output voltage, an internal power supply configured to step down the input voltage to generate a predetermined internal power supply voltage, a reference voltage generator configured to generate a predetermined reference voltage from the internal power supply voltage, an amplifier configured to generate a drive signal for the output transistor such that a feedback voltage in accordance with the output voltage is equal to the reference voltage, a drive current generator configured to generate a drive current for the amplifier, and a drive current controller configured to detect a variation of the internal power supply voltage to variably control the drive current.
