hi,
where can i find current limit circuits (for 50ma current)example to build from scratch,
and is there any ICs that do that as a singke solution?
thanks for any help...

You must use a JFET with IDSS > 50mA
Check also power dissipation in the JFET
Here is my curves from Proteus (not the same JFET !) :
The resistor biases negativly the Gate.
You must adjust resistor to catch your current limiting value.
