It’s also not such a bad idea to run a switcher ahead of the LM or to keep the voltage just above that which is needed for the device roughly 3v higher than Vout. In addition, do you think it’d be worthwhile to put a constant load, like a 20K resistor or something on the output, just to give the regulator a minimum load?
Perhaps a large cap from ADJ pin to ground would help. A brand-new, unused, unopened and undamaged item in original retail packaging where packaging is applicable. For some reason, after a computer restart I can now see your schematic.
