1.5A Constant Current Linear Regulator for LEDs for

Step 2: What else do we need? How bout 5V@20mA

Because I wanted this design to have a nearly identical pinout as the BuckPuck from Luxdrive I decided to add a simple 5V@20 mA

Slowly getting this figured out.  A couple quick questions though.  D5 in the schematic is a Zener diode.  But in the BOM you list an LED driver for D5.  Confused.

Also, the schematic shows C1 and C3 as 4.7uF and the BOM lists them as10uF and 1uF.  Which should I use?
Thanks

These schematics are too small to read, and I don't get any usable GIF when I try to right-click-save them to view them another way.

Any chance of putting this up on a blog entry (or elsewhere) on your website...?

 ewertz, I added a .pdf schematic that should be much easier to read to step 2.
