Hello, I'm a Computer Engineering student currently and am building a 120vac to 5vdc power supply.
This is my circuit thus far. It works, but as you can see I'm getting only 4.85v from the regulator.
The real question I have is I wanted to put in a lighted rocker switch. I bought one and placed it in between the 12vac and the diode bridge. I connected terminals 1 and 3 on the rocker switch only. The problem with this is that the switch is bright when first turned on then dims and shuts off after about 2 seconds. I tried placing a 100ohm resistor as a load as depicted in the picture but the voltage dropped from 4.85 to about 2.5. Why?
