Large supercomputers, small pocket calculator, all electronic devices must be more support in the power circuit to work properly. Commonly used with AC and DC power supply of the points, of course, the power supply circuit style, complexity vary widely. Undeniable power has been widely used in all aspects of our lives, so learn and understand the power of production principles and techniques for our production and development and many have a positive meaning. As characteristic of electronic technology, electronic circuit design equipment for the power requirement is to provide a steady, full of energy load requirements, and usually require a stable DC performance. This can provide a stable DC power supply is DC regulated power supply. DC power supply in power supply technology plays a very important position. In this paper, design and production figures show that the DC power supply. The power supply as a mini-starter with adjustable voltage regulator range 1.25-20V, and output voltage can be displayed with the function. This article describes the display sectio
