<p>Provided is a small regulator device that has a plurality of outputs and that is capable of generating an output voltage for which there is a high requirement for stability. This invention is therefore provided, e.g., with an input node into which is supplied an input power supply voltage (VIN), a first output node in which is generated a first output voltage (VOUT1), a second output node in which is generated a second output voltage (VOUT2), an inductor (23), capacitors (C24, C29), switching elements (25-28), and a power supply controller (22). The power supply controller (22) is set in advance with a first range of a control threshold, controls the ON/OFF of the switching element (27) so that the first output voltage (VOUT1) shifts in the first range, and controls the switching element (28) to ON while the switching element (27) is OFF.</p> |
