概述

Description

The LT3080EDD-1 is a precision adjustable linear voltage regulator produced by Analog Devices. It offers a simple and efficient solution for voltage regulation in various electronic applications. The regulator can supply a maximum output current of 1.1A with a dropout voltage of 350mV at 1A, making it suitable for low-voltage applications. A key feature of the LT3080EDD-1 is its ability to provide a wide output voltage range, adjustable from near zero to 36V, set via a single resistor. It has a reference current source that ensures accuracy and stability.
The device includes several protective features, such as thermal limiting and current limiting, which safeguard against over-temperature and over-current conditions. Additionally, its low quiescent current and shutdown capability enhance power efficiency. The LT3080EDD-1 comes in a thermally enhanced 8-lead DFN package, ensuring efficient heat dissipation. Its robust design and versatile features make it ideal for use in industrial, telecommunications, and consumer electronics applications where precise voltage regulation is critical.

Features

The LT3080EDD-1 is a low dropout (LDO) linear regulator known for its precision and versatility. It features a wide input voltage range of up to 36V, providing an output current of up to 1.1A. A distinctive feature is its single resistor setting for the output voltage, which can be adjusted from 0V to 34.5V, offering flexibility for various applications. The device ensures excellent regulation and transient response, with a low dropout voltage typically around 300mV at full load.
The LT3080EDD-1 also includes a current limit and thermal protection for enhanced reliability. It has a low output noise of typically 40μVRMS, making it suitable for noise-sensitive applications. The regulator is designed to operate efficiently with a small output capacitor and features a shutdown pin for minimizing power consumption when not in use. Additionally, it includes a current reference that can be used for current sharing and paralleling devices to increase output current. Packaged in a thermally enhanced 8-lead DD package, it is optimized for space-constrained designs.
