    Abstract
    In electronic system, device failure will occur due to different things one of them is
    lack of giving right amount of electricity for our devices (variation of input voltage,
    and the load current).This problem is solved by Voltage regulators. Voltage regulators
    are used to offer fixed voltage at the output terminal and does not depend on the
    variations at input voltage supplied temperature and load current (as long as it is
    greater than the required voltage). They are available invariant of output like 5V, 6V,
    9V, 12, and 15V. But to get the desired regulated output voltage within the range is an
    issue. The main purpose of designing Variable Power Supply System from Fixed
    Voltage Regulator is to provide desired regulated output voltage within the range by
    taking single linear voltage regulator IC as its heart. It works under dual purpose that
    means through converting of a varying input voltage into constant regulated output
    voltage by voltage regulators, and the output of voltage regulator can be increased by
    using pair of voltage divider resistors. The system has been constructed by taking
    some electrical components, and devices, but they have enormous importance like
    Step Down Transformer, Capacitor, Resistors, Voltage Regulator IC, Rectifier, mini
    breadboard, and connecting wire are used Furthermore it has been designed, and
    analytic ways as well as the final simulation result is pointed by using PROTEUS
    Software.
