Hai,
I want to use LM338 Regulator with adjustable Voltage & const 2A/adjustable current configuration. Can I use the fallowing configuration to let me adjust both current/voltage.In this case All I need is 0-24V@2A. I am thinking that I can adjust voltage by changing R3 and can adjust current by changing R1. Is that posiible?
Also I want to use a separate 5V regulator in parallel to the above to power some additional circuitry.Can I use DC-DC converter or a small transformer even to feed 5V regulator. I don't want the 5v regulator taking all the load of my main transformer, when the main regulator ckt is off(LM338). I want to use 5V@100mA of current only,irrespective of the main ckt is on/off. Can anyone help me in this matter...
thanks
