transients 34 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 LTВ®3080, 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.
THE OLD WAY In the old linear regulator architecture (Figure 1),
feedback resistors set the output voltage and attenuate …
