概述

Description

The LT3080EDD is a low dropout (LDO) linear regulator designed by Analog Devices. It is known for its simplicity and precision in providing a stable output voltage. Key features include a wide input voltage range, typically from 1.2V to 36V, and the ability to deliver up to 1.1A of output current. One of its standout characteristics is the use of a single resistor to set the output voltage, which enhances ease of use and design flexibility.
The LT3080EDD offers low dropout performance, meaning it can regulate the output voltage even when the input voltage is very close to the desired output. This feature makes it suitable for applications where efficiency is crucial. Additionally, it includes protection features such as current limiting and thermal shutdown to prevent damage under fault conditions.
Its small footprint and high performance make the LT3080EDD ideal for a variety of applications, including telecommunications, industrial systems, and other electronic devices requiring efficient power regulation.
