Product Details

Demonstration circuit 1447A is an adjustable 200mA linear regulator featuring LT3082. Architected as a precision current source and voltage follower, it allows this new regulator to be used in many applications with adjustability to zero output. The LT3082 has an input range of 1.2V to 40V, but the demo board limits this range to 2.8V to 35V. The LT3082 withstands reverse input voltages and reverse output-to-input voltages without reverse-current flow.

Features and Benefits

  • Analog Devices has worked closely with Intel PSG to develop verified power solutions that optimize cost, size and efficiency in high performance applications.
  • The validated power solutions include uModules power products that address time and space constraints while delivering high efficiency, reliability, and low noise.
  • The actual power tree represents the best solution at time of design.
  • A recommended power tree has also been included to present the ideal solution at time of Stratix 10 GX SI development kit release. An updated alternate version of the power tree represents the latest solutions available from Analog Devices. For many applications, an intermediate rail is not ideal, so recommendations for an alternate power tree that allows for direct power conversion from 12V input is provided below.
