Part Number: LM134

Hi,

I am working on a micro ohm meter. So do you have any ref design ?

For this I want a Constant current source for 1A,100mA & 10mA, Can you help me to design this type of source ?

Hello,

For high current outputs like 1A and 100mA, you can use a circuit such as this and adjust Rs.

Thanks,

Walter

Is it possible to do using a LM317 ?

Pls find the attached picture.

Yes that circuit will work if you use a LM317 variant capable of 1.5A.
