LMS1587 IC ADJ Voltage Regulator Texas Instruments LMS1587CT-ADJ/NOPB

Product Overview

A high-current, low-dropout (LDO) positive linear voltage regulator designed to deliver a highly stable, customizable output voltage ranging from 1.25V to 5.75V. Capable of sourcing up to 3A of continuous output current, this device is engineered for applications demanding fast transient response and robust power delivery under heavy loads, such as high-efficiency post-regulators for switching supplies, battery management systems, and microprocessor supply lines. Operating reliably across a broad temperature range (-40°C to +125°C), the integrated circuit features a low 10mA quiescent current and incorporates critical safety mechanisms, including built-in overcurrent protection and thermal shutdown, to guarantee long-term system durability.
