LM2575-XX Buck Regulator

2 layer board of 0.63x1.32 inches (16x34mm). $4.15 for three.

Got the idea from here

More or less a LM7805 dropin replacement (maybe 40% larger) I designed it for maximum copper pour under the IC for heatsinking, got the initial design from here and just tweaked it out…there are commercial products that do the same thing, are smaller and more than likely much cheaper here and here and here My design is more or less for the DIY crowd…

By getting the 3.3v, 5v, or 12v LM2575 you can have different output voltage

LM2575 3.3v IC here , 5v IC here and 12v chips

C1 and C2 are 100 uF 153 CLV 0605 series metal SMD capacitors here

Inductor L1 is 330 uH DR127 here

Diode D1 is SOD123 here
