Hello I'm new to integrated circuits. Someone suggested the L200C regulator as a current regulator/ voltage regulator for my project but I don't really understand how it works. What are each of the Pina for on it. How do you hook it up to get it to be either a current regulator or voltage regulator and how do I get a steady 5volts at 2amps from it. Is there anywhere on the net I can learn more about it. Thanks.

Yes it was me...
Here is a circuit that uses the L200c regulator, current limit is set with the resistor between pins 2, 5..

Iout=0.5V/ R-limit

The voltage output is the same as other regulators (V= (1+R2/R1) x 2.75)

Hello,

@Dodgydave , The given formulas do not have the correct values.
The current will be : Iout = 0.45 / R-limit
The voltage will be : Vout = 2.77 * (1+R2/R1)
