Voltage regulator using only discrete components. Replaces the 7805 5V regulator chip. Sine wave input is to show "ripple" voltage. Output is smoothed with barely discernible ripple. Adjust the pot to see effects.

Output is ~5V if input is between 10V and 15V. Current config has an output ripple of 0.04V.
