Key Featrues

Extended Safe Operating Area (SOA): The LT3081's extended SOA ensures reliable operation under high current and voltage conditions, making it ideal for rugged industrial applications where stability and durability are critical. This feature enhances performance by preventing thermal runaway and ensuring consistent output even in demanding environments.
Single Resistor Output Voltage Setting: The ability to set the output voltage using a single resistor simplifies circuit design and improves flexibility. This feature allows for easy customization of the output voltage, making the regulator suitable for a wide range of applications, from low-voltage supplies to higher-voltage requirements.
Output Current Monitor: The integrated output current monitor (IMON = IOUT/5000) provides real-time feedback on the load current, enabling precise control and monitoring of power consumption. This feature enhances efficiency by allowing users to optimize power usage and detect potential issues early.
Reverse-Battery and Reverse-Current Protection: The LT3081 is designed to withstand reverse input and reverse output-to-input voltages without reverse current flow. This protection feature increases reliability and safety, particularly in automotive and industrial applications where accidental reverse connections are possible.
Parallel Operation for Higher Current or Heat Spreading: The ability to parallel multiple LT3081 devices allows for higher output current or improved thermal management. This feature is beneficial in high-power applications, as it enables scalability and better heat dissipation, ensuring stable operation even under heavy loads.

Applications

Rugged Industrial Power Supply: The LT3081 is ideal for providing stable and reliable power in harsh industrial environments. Its extended safe operating area (SOA) and robust design ensure reliable operation even under extreme conditions, making it suitable for powering industrial machinery, automation systems, and heavy equipment.
Post Regulator for Switching Supplies: The LT3081 is perfect for use as a post regulator in switching power supplies. Its low dropout voltage and high PSRR (Power Supply Rejection Ratio) ensure clean and stable output voltage, making it suitable for applications where noise-sensitive circuits require precise voltage regulation.
Low Output Voltage Supply: The LT3081 is well-suited for applications requiring low output voltages, such as powering microcontrollers, FPGAs, and other low-voltage digital circuits. Its ability to adjust the output voltage down to 0V ensures compatibility with a wide range of low-voltage devices.
Intrinsic Safety Applications: The LT3081 is ideal for use in intrinsic safety applications, such as those found in hazardous environments like oil and gas facilities. Its programmable current limit and reverse-battery protection features ensure safe operation, making it suitable for powering equipment in potentially explosive atmospheres.
