Simple Regulator Circuits with current limit by FET

Here the circuit has been modified to provide current limiting to reduce the output voltage if too much current is demanded. This will reduct the possibility of damaging equipment by drawing excessive current. All component values not marked are the same as in the previous circuits. R1 = 0.7 / Amperes.

* R1 = 10 ohms for 60 mA
* R1 = 7 ohms for 100 mA
* R1 = 2.5 ohms for 300 mA
* R1 = 1 ohm for 700 mA
* R1 = 0.7 ohms for 1 A
* R1 = 0.25 ohms for 3 A
