LM134/LM234/LM334 3-Terminal Adjustable Current Source

Hi, I am look for any low current alternative that I could use that are three terminal adjustable current like the LM134/LM234/LM334. I am mainly looking for alternatives because the simulation program I am using, ni multisim, does not have any spice or models I can use in that environment. All help is welcomed so I can finish this project. Thank you very much.

Best,

Bobby

 

Thanks Dave for the reply and thank you for the welcome. I am glad to be able to get some help. I am going to look over the two data specs on the LM317 and the LM334. (I am printing them out as I type this) While I am doing so what is the main difference between the two?

Again thank you,

Best,

Bobby

 

Hi,

After looking over the two and looking at the project I am trying to accomplish, I would really like to go with the LM334. The only problem is I cannot find a spice model for it any where so I can complete this circuit. Seems to be a little frustrating. Any help be great. Thank you.

Best,

Bobby
