On page 19 of the LT3083 there is a lab PSU which I have made. However the voltage varies at a very unpredicted way, like a logarithmic way when completely unloaded. Also when completely unloaded the voltage output climbs much higher to about 14v.
When I connect a small 12v incandescent panel indicator bulb at the output the voltage setting is smooth as it should.
But even then i can produce a max of 9v.
Second problem, I loaded it with a device drawing 250-500mA at 9v and it is like pulsating on/off
What is the problem?
