Regarding the previous post concerning TL783 behavior below 0C, I want to thank TI's Ron Michallik for expert insight. He emailed me saying there are no easy pulse 5A solutions, to which I agree, therefore I'd like to paste the below links that may be of help to someone else in this area.

On a final note, a legendary designer passed away recently that many of us are familiar with as the author of the "Pease Porridge" collumn.
http://en.wikipedia.org/wiki/Bob_Pease
Robert A. Pease (August 22, 1940 – June 18, 2011) was an analog integrated circuit design expert and technical author.[1][2] He designed several very successful "best-seller" integrated circuits, many of them in continuous production for multiple decades. These include the LM331 voltage to frequency converter,[3] and the LM337 adjustable voltage regulator. Pease was killed in the crash of his 1969 Volkswagen Beetle, on 18 June 2011.[13][14][15] He was leaving a gathering in memory of Jim Williams, who was another well-known analog circuit designer, a technical author, and a renowned staff engineer working at Linear Technology. Pease was 70 years old, and was survived by his wife, two sons, and three grand-children.
