They're supposed to run hot, but excess temperature will degrade the stability 
and shorten the lifetime of the electronics. It's hard to recommend what 
heatsink they require if you have no documentation. Typically you'll need one. 
My LPRO-101 need a heatsink with < 2K/W of thermal resistance to keep the 
temperature in check.
