Please see attachments.
I found a beginner power supply project online (first image). In it the author shows protection diodes attached from output to input of the regulators. The second image is a capture from the regulator mfg datasheet which shows the same diodes already mentioned as well as two others connected from the adjustment leg to the regulator outputs.
Since this is a refresher for me while I return to the world of electronics
, my question is whether the extra two diodes the project author didn't include are really necessary or not? His pcb pattern for the project only accommodates the two he included in his schematic but I figure it would be easy enough to add the other two in.
Suggestions please?
Thanks for your help in advance.
