Maybe were getting mixed up on part numbers here. Linear Tech has linear and switching regulators. Their linear regulators are pretty much the same as the LM1084 series. Linear regulators are not very efficient, basically divide input and output voltage to come up with the efficiency. The Linear technologies switching regulators are just the chip, yo ustill have to add the coil, and other parts. I saw these TI and they are as simple to connect as a linear regualtor, but are switching. When I started soldering up my linear regulator power supply, it grew in size and I would have to add anothe pcb to the side of my system to fit all the parts while maintaining enought space for mounting them to the heatsinks. If I use the TI ones, I get space savings because I don't need heatsinks, I will probabally get the tabbed ones and put some heatsink grease and mount them to my chassis just to be safe, but I can really simplify my design.
