DESIGN AND ANALYSIS OF ULTRA LOW POWER VOLTAGE AND CURRENT REGULATORS

This project provides the scholastic presentation regarding the techniques and circuits used in ultra-power switching regulators. They were generally used for limiting the voltage and to make the fluctuations stable or constant. Methods dealing with the switching Regulators will generally cause specific issues like short circuits, thermal run away etc. by covering both lower and higher switches. In the design of switching circuits like voltage regulators, we make sure that if any voltage fluctuations exist, we stabilize it and this project also includes to make both the high and low currents into a stabilized current using different transistor cells, which are used in many applications in order to get rid of damages. It works on the phenomenon of UVLO i.e. “Under voltage lock out. In case if any input voltage drops below the UVLO, it detects the voltage during operation and forces to stand by stable state to prevent the malfunctioning. When the input voltage rises above the UVLO released voltage again, the UVLO releases into initial voltage .Thus, we have chosen this project because now-a-days the need of ultralow power switching circuits are increasing due to their high demand as they offer more pros of high power conversion ratio, better efficiency and flexibility.
