Regulator earns award from Power Electronics Technology magazine

11 June 2008 News

Power Electronics Technology magazine selected Linear Technology's LT3080 3-terminal low dropout linear regulator as its 2007 Product of the Year.

The award was presented at the Power Electronics Technology Conference in Dallas to Linear Technology vice president Engineering and chief technical officer Robert Dobkin, who developed the product.

David Morrison, editor of Power Electronics Technology, stated, "Among the hundreds of power components introduced each year, there are numerous devices with exciting performance improvements and novel features. This continuing wave of innovation makes selecting a single product for special recognition a particularly daunting challenge. Linear Technology's LT3080 was selected as this year's Product of the Year because it offers an intriguing combination of novelty and usefulness. By redesigning the low-dropout linear regulator, Linear has given engineers an extremely flexible building block that should help solve current and future board-level power challenges."

The LT3080 is a 1,1 A 3-terminal linear regulator that can be paralleled for heat spreading and is adjustable to zero with a single resistor. It uses a current reference and voltage follower to allow sharing between multiple regulators with a small length of PC trace as ballast, enabling multi-amp linear regulation in all surface-mount systems without heatsinks.

The LT3080 achieves high performance with wide input voltage capability from 1,2 V to 40 V, a dropout voltage of only 300 mV and millivolt regulation. The output voltage is adjustable, spanning a wide range from 0 V to 40 V, and the on-chip trimmed reference achieves high accuracy of ±1%. The device is well suited to generating multirail systems.
