LM317T Voltage Regulator with Pass Transistor

Here is video of Adjustable Regulator using LM317(3-Terminal Adjustable Regulator).The LM117 series of adjustable 3-terminal positive voltage regulators is capable of supplying in excess of 1.5A over a 1.2V to 37V output range.Here is very simple circuit having Two Capacitors , One Register Pot and LM317.The value of Pot is chosen so that my output voltage vary between 0V to 0.55V (DC).
