Hi, I'm designing a pcb power supply for a router project. I am building it in pspice. The power main will be standard wall outlet 120VAC 60 Hz.
The output needs to be 5VDC and 2 amps output for what is being powered.
I was looking for help in selecting:
-12:1 transformer
-full bridge rectifier
-voltage regulator

Please keep in mind the 2 amps that are needed to be drawn. Thanks.

Attached is what i have done up in Multisim.

DigiKey have the components you need, the transformer is Hammond HM514-ND unless you need through-hole.
You may want to fuse it also.
