variable current regulator schematic ?

[thebadtall]

Hello I am interested in making a variable current regulator, and found some info about the L200 ic
**broken link removed**
But instead of L200 can you suggest something else ? (for up to 2A)
Thank you

You are asking for constant V/ constant I like L200 or constant I only?

Hello, I am actually interested in variable current ,and secondarily in variable voltage .
However, I focus on variable current, as I can regulate the voltage on a previous section

Constant I can be easily made with LM317 respectively LM350 for > 1.5A.
L200 is somehow unique in the simple constant I/V configuration.
There are example schematics for I/V regulation in the LM337/350 datasheets, but they need a lot of additional components,

I will finally try the L200 approach ! Thank you
