Abstract
A switching regulator according to the invention includes a resistor (R) and a capacitor (C) for generating a ramp signal from the AC component in the output of a hysteresis comparator (). The switching regulator is characterized in that the hysteresis comparator () compares with a reference voltage outputted from a reference voltage source () a voltage obtained by superimposing the ramp signal on the divided voltage of the output voltage (V) as obtained between resistors (Rand R).
