Design and build a dual input negative linear regulator

Abstract

With the advent of Integrated circuits and the widespread proliferation of direct current based consumer electronics such as smartphones, voltage regulators that are capable of providing a stable DC voltage from an AC power source have become essential to the everyman. A voltage regulator is able to maintain a stable voltage as it senses changes to load conditions and adjusts a voltage divider internally. The purpose of this project is to design and construct a dual input, negative voltage regulator able to switch between -6.3V and -13.3V inputs automatically depending on load condition. Methodology and results obtained will be elaborated further in the report.
