Product Summary

The a8296sestr-t is a single low noise block converter regulator which is a monolithic linear and switching voltage regulator, specifically designed to provide the power and the interface signals to an LNB down converter via coaxial cable. The a8296sestr-t requires few external components, with the boost switch and compensation circuitry integrated inside of the device. The a8296sestr-t has been designed for high efficiency, utilizing the Allegro advanced BCD process. The integrated boost switch has been optimized to minimize both switching and static losses. To further enhance efficiency, the voltage dropacross the tracking regulator has been minimized.
