The Linear LT3080ET#PBF is an adjustable low dropout linear regulator designed to provide maximum output current of 15A with high efficiency. It is specifically designed for power applications requiring high current supply and low input voltages. The LT3080ET#PBF has an integrated thermal protection circuit that helps protect it from over-temperature operation which can be caused by excessive power dissipation. The LT3080ET#PBF is ideal for applications requiring ultra-low power levels, such as in solar cell or battery-powered systems.

The structure of the LT3080ET#PBF consists of two physical stages: a pre-regulator and a linear regulator. The pre-regulator stage is composed of a fixed frequency 10mA step-down switching regulator, while the linear regulator section is used to regulate the output voltage from the pre-regulator. The output voltage can be adjusted from an external resistor divider connected to the device\'s Adjust pin. The Adjust pin also provides information about the output voltage to the external voltage feedback circuitry to regulate the output voltage.

The LT3080ET#PBF is capable of operating with an input voltage ranging from 2.5V to 38V, making it suitable for applications that are powered from batteries, wall adapter, solar panel or other power sources. The operating junction temperature range of the device is -40°C to 125°C, which is suitable for a wide array of industrial, consumer, and automotive applications. The device also has an integrated programmable soft-start function that can be used to reduce inrush currents at start-up. The current-limit of the device is user selectable via an external component, allowing the user to set the output current limit as needed.

The LT3080ET#PBF has a wide range of uses, such as it can be used to power LED drivers, DC motors, servos, and other high current applications. It can be used for applications where ultra-low power levels are required, such as portable devices powered by a single cell lithium battery. It can also be used in applications where high efficiency is required such as motor drivers, switched-mode power supplies, and power-conversion circuits. The device is also suitable for powering low-dropout regulators, which are widely used in wearables and IoT applications.

The LT3080ET#PBF can be advantageous in many applications as it has very low dropout and high output current capabilities. It also has low output voltage noise, low quiescent current, and fast transient response, making it suitable for high-performance applications. The device is also designed to operate at a fixed frequency, eliminating the need for an external oscillator and reducing the number of components and board space required. Finally, the device is equipped with a thermal protection circuit, ensuring its safe operation and reliability in harsh environments and under arduous conditions.
