LT3082EST#PBF - Low-Dropout Adjustable Linear Regulator

The LT3082EST#PBF is a versatile, adjustable linear regulator from Linear Technology, designed to cater to a wide range of power supply applications. This innovative component introduces a new architecture to extend the capabilities of linear regulators, offering significant improvements in performance and flexibility.

At the heart of the LT3082EST#PBF is its ability to deliver up to 200mA of continuous output current with a dropout voltage of merely 300mV at full load. This makes it an excellent choice for systems that require a stable and precise voltage supply, even when operating with a very low differential between input and output voltages.

One of the standout features of the LT3082EST#PBF is its adjustability. The output voltage can be set anywhere from 0.4V to 32V with a single resistor, and without the need for any additional external components, such as bypass capacitors. This simplicity in design not only reduces the overall component count but also minimizes the footprint on the PCB, saving valuable space in compact electronic designs.

The regulator also boasts excellent thermal performance due to its power package, the SOT-223, which provides effective heat dissipation. This ensures reliable operation even in environments with elevated temperatures. Additionally, the LT3082EST#PBF features internal protection mechanisms, including current limiting and thermal shutdown, which safeguard the device and the system against excessive current and overheating.

For applications requiring low noise performance, the LT3082EST#PBF excels with its low output noise characteristic of only 40µV_RMS over a 10Hz to 100kHz bandwidth. This makes it suitable for sensitive RF applications, precision instrumentation, and other noise-critical systems.

In summary, the LT3082EST#PBF from Linear Technology is a highly adaptable and efficient linear regulator. Its ease of use, combined with its robust feature set, makes it an ideal choice for designers looking to optimize their power management solutions with minimal complexity and maximum reliability.
