A8297 Datasheet Dual LNB Supply and Control Voltage Regulator

Manufacturer: Allegro MicroSystems

General Description

Intended for analog and digital satellite receivers, this dual 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 A8297 requires few external components, with the boost switch and compensation circuitry integrated inside of the device.

A high switching frequency is chosen to minimize the size of the passive filtering components, further assisting in cost reduction.
