概述

Description

The LT3090EDD#TRPBF is a low dropout (LDO) linear voltage regulator produced by Analog Devices (formerly Linear Technology). It features a maximum output current of 1A and offers low dropout voltage, making it suitable for applications where power efficiency is critical. The device is designed to provide a stable output voltage with high power supply rejection ratio (PSRR), which helps minimize noise and ripple in sensitive circuits.
Key specifications include an output voltage range adjustable from 0.1V to 15V, thermal protection, and short-circuit protection. The LT3090 also supports a wide input voltage range, typically up to 15V, and operates efficiently at low quiescent currents. The EDD package type indicates it's offered in a compact, thermally-enhanced surface mount package, providing ease of integration into various electronic designs.
This regulator is commonly used in battery-powered devices, RF applications, and precision analog circuits where low noise and high stability are essential.
