Hi to all!!!
I am designing a 7.5V 2A power supply using LM338. Now it's a basic circuit likeAC 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 specificationmains 230V 50Hz AC, T112 VAC10 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???
