Hi to all!!!
I am designing a 7.5V 2A power supply using LM338. Now it's a basic circuit like---AC 230---->Transformer 12VAC 10Amp.--->Bridge Rectifier--->Filter(using Capacitor)--->LM338 (setting R2/R1)--->Vout with Capacitor....
I am posting the circuit diagram ,can any one tell me how to decide the values of all capacitors...
My specification---mains 230V 50Hz AC, T1-12 VAC-10 Amps..,I want Vout=7.5V and 2Amp.
See figure ..
Can you tell me how to determine values of C1 to C5....also diodes D1 and D2 are there.... If I am not wrong D1 is for protection,and what about D2???
