LT3097 in Parallel

Question

Hello, Is it possible to parallel two or more LT3097 devices in order to increase the output current for each of the output rails? Thanks Sariel,

The regulators don't have explicit design accommodations for being paralleled, but you can use ballast resistors to get reasonable matching at the expense of a bit of increased load-line behavior. 
 The inner control architecture is the same as several other LT30xx linear regulators. The LT3042 datasheet provides some commentary on paralleling multiple regulators, so I'd suggest looking at that datasheet. One of the typical applications in the datasheet provides a method of attempting to use some extra ILIM circuitry to counteract the effect of the ballast resistor.)
