Adjustable version output voltage range: The LM series operates at a switching frequency of kHz, thus allowing smaller sized filter components than what would be needed with lower frequency switching regu- lators.

Requiring a minimum number of external components, these. I had a similar experience when I first got into switching regulators and used an inappropriately sized inductor, which would regulate for small loads and drop to near 0V for large ones, the inductor had fried and seemed to make contact when there wan’t much heat generated in the coil and was open when it heated up.
