It was the diode around the wrong way. Okay so I change the input capacitor to uF electrolytic and the output to 47uF.

Cb is shown in the data sheet as 0. I followed the instructions in the LM datasheet. Yes, my password is: I used the following equation as per the datasheet: Buck Converter Output Voltage Posted by notoriusjt2 in forum: I didn’t think it was wrong because the previous one I built had it that way and still worked.
