The architecture of linear regulators has remained virtually unchanged since the introduction of the 3-terminal floating voltage regulator in 1976. Architectures have settled on either the floating architecture (LT317) or an amplifier loop with feedback from the output to the amplifier. These architectures inherently limit regulator versatility, regulation and accuracy. In 2007, Linear Technology released the LT3080, introducing a new linear regulator architecture that expanded versatility, significantly improved performance, and allowed easy parallel operation. The LT3081 is one of this new class of linear regulator, specifically featuring a wide safe operating area for industrial applications.
