A8305 Overview
Intended for analog and digital satellite receivers, this single low noise block converter regulator (LNBR) 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 A8305 requires few external ponents, with the boost switch and pensation circuitry integrated inside of the device. A high switching...
