Circuit 2

For my second circuit, I was making a voltage regulator to turn a 12v input into a 5v output.

To achieve this, i used a LM317T, among other components. 

In this circuit, other than the voltage regulator itself, i used: 

2 x Capacitors

1 x 5mm LED

2 x 1n4007 Diodes

1 x Zener Diode

1 x 150ohm Resistor

1 x 220ohm resistor

1 x 680ohm resistor

After completing this circuit and testing, i found that it was working correctly without modification.

My readings across the circuit were as follows:

Vs=12v

Vs@LM317=5.17v

Vd@R1=1.24v

Vd@R2=1.25v

Vd@R3=3.92v

Vd@LED=3.94v

From this circuit, i now have a stable 5v supply output, plus another 12v RAW output.
