I sugest you use de L200. It's an voltage and current regulator. Wich
opperates from 2,6 to 36V and has an max current of 1.5
De application schematics will help you to complete the job

Hi,

Thats a theoretical impossiblility. The only way to make a supply with
a specific current is by letting the voltage vary. You cant both
specify the voltage and current with anything but the R=E/I (resistive)
load value.
