Your supervisor has also passed on to you a power supply circuit sketch to upgrade your last power supply (Assignment 1) so that it has a Fixed 5V regulator output and a Variable Voltage Regulator output. . Analyse the variable regulator section (containing the LM317 IC) and determine the expected output voltage range the circuit should achieve by the range of adjustment of the 1k potentiometer. Build the circuit and verify the voltage range available. Ensure it can achieve 12V within its range. Tabulate the expected and measured ranges.
