A few weeks ago we were discussing paralleling regulators .
The October 2007 bulletin from Linear announces a new part : the LT3080 low
drop regulator. They claim: "The LT3080 is the first adjustable linear
regulator that can be directly paralleled to spread the current load and
thus spread dissipated heat." The architecture is based around a precision
current source rather than the typical precision voltage reference. The
output potential is set with a single resistor when in typical 3-terminal
configuration and can be taken all the way down to zero.
