Hello everyone. I'm hoping somebody can help me with this.

Attached is the circuit I use to obtain 5V for most of my microcontroller projects. I'm hoping somebody can show me a better way which results in a more compact board and uses less parts.

Is it possible? Thanks a lot.....JDR04

That's about as simple as it gets and just what I do.

The only thing simpler is to use a regulated 5V wall wart.

There are regulators that work with 4.7uF (or less) cap at input/output. All available in small footprint (603 caps).

The 100uF on the input maybe too small, depending on the load current, especially considering half-wave rectification; full-wave would be better.
The 100uF on the output is too big. Go with what is recommended on the regulator's data sheet.
