Hi, heres a power supply i designed to deliver 5V and 3.3V. Can anyone tell me if it will work.

Any help is much appreciated. Thanks

 

Sorry, i forgot to attach the circuit digram.

 

Change R1 to 120 Ohms. Change R2 to 200 Ohms.

For more stability, connect a 10nF cap between the junction of R1/R2 and ground.

You need larger filter caps after the rectifier bridge. 2,200uF would be OK for up to around 500mA.

Don't forget to use heat sinks.
