Overview

Product Details

Demonstration circuit 1585A is an adjustable 3A linear regulator featuring the LT3083 in the DD-PAK-5 package. Architected as a precision current source and voltage follower, the LT3083 can be used in many applications requiring high current, adjustability to zero output, and no heat sink. Internal protection circuitry includes current limiting and thermal limiting.The device brings out the collector of the pass transistor to allow low dropout operation when used with multiple supplies.


The demo board oprerates with an input supply voltage range of 1.7V to 23V. A control voltage bias supply that is 1.2V to 1.4V higher than the input voltage is required for proper regulation. A key feature of the LT3083 is its wide output voltage range. The DC1585A's jumper-selectable output voltage can be set to 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5.0V, or a user-selectable value. DC1585A can be used as a high current linear regulator, a post regulator for switching supplies, a variable voltage supply or a low output voltage power supply.
