Thanks but demand of my current is about 1.7A so 5 A is very too,Sorry, I meant "adjustable" as well (implied). I use the LM338 types myself, very seldom any fixed regulator except for the 5V ones for digital circuits....
The LM338 is rated for 5A.
The LM338 will handle "up to" 5A. It does not mean you have to draw that much current. Based on that Youtube video, you can make a 1.6A current source with either the LM350 or LM338 with a 0.78 ohm resistor, very close to 3/4 ohms. You will likely have to use a combination of resistors to get the value you want.Thanks but demand of my current is about 1.7A so 5 A is very too,
Do you work with lm350 for that application?

The resistor should be rated at least at 2W heat dissipation in total, as it will dissipate that much heat. A 3W minimum to a 10W resistor would be best.
And, as chemelec says, you will need a heatsink for whatever regulator you choose.
