Thank you for the answers! I'll have to make more exact my question. I need a circuit of a linear regulator with following parameters: Vin=220±10% with frequency=50 Hz, Vout1=6.3 v, Vout2=-6.3 v, I(load)=5.5 A, stabilization factor>=150.
This circuit should be designed with using IC. I assume it is simple for you. Please hint me something (what ICs i should to use, and something about appearence (figure) of the scheme). I'm sorry for my bad English.
