I am designing 7.5V , 2Amp. power supply from 230 V,50 Hz. AC using LM338,
230V to 9V ,2.5Amp. transformer...
Now, after some working out here in forum, I found my Filter capacitor value around 16667uF....
However, one other important term I come to know is Inrush Current limiter...
For, that I found two common technics 1.Resistor and 2. NTC thermistor method..
Now, the question is how to find out which value is suitable for my application???
some links for details..\
