  • I'm having trouble with oscillation on what is (I think) an inductive load. It's a gas regulator valve expecting 100 to 400mA current, but it seems to bounce partially open/closed at ~10Hz unless I ramp up the current very slowly. Power supply is a switching 12V 3A voltage source.

    Edit: I solved the oscillation(output ripple) in my inductive load by increasing the capacitance that was in parallel with the load(Sparkfun C1). According to the AL8805W5 datasheet, increasing capacitance on the output will increase startup delay, but that didn't matter for my application. A change from 1uF to 4.7uF did the trick.

No public wish lists :(
