LM1084ISX-5.0/NOPB

Overview

The LM1084ISX-5.0/NOPB is a Texas Instruments positive low-dropout linear regulator providing a fixed 5.0 V output with a maximum continuous current of 5 A. It operates within an input voltage range of 2.6 V to 25 V and features a typical dropout voltage of 1.3 V, reaching a maximum of 1.5 V at full load. The device includes internal thermal shutdown and current limiting protection. It is housed in a surface-mount D2PAK-3 (TO-263-3) package and supports operation across an industrial temperature range from -40°C to +125°C.

Feature Summary

Provides stable 5.0 V regulation with high 5 A output current capability
Integrates thermal shutdown and current limit protection for robust operation
Features low dropout voltage for efficient power management under varying loads

Applications

Post-regulation for switching DC/DC converters
Battery charger circuits requiring precise voltage control
General-purpose linear power supply stages

Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status as per the manufacturer's latest documentation. Confirm the 'ISX' designation corresponds to the correct TO-263-3 surface mount package variant. Ensure the fixed 5.0 V output version matches the system requirement, distinguishing it from adjustable or other fixed voltage variants within the LM1084 family.

Selection Notes

Select this component when a fixed 5.0 V rail is required with up to 5 A load capacity. The D2PAK-3 package offers suitable thermal performance for surface mount designs. Consider the 25 V maximum input rating and 1.5 V dropout characteristic for headroom calculations. This part is appropriate for industrial environments due to its extended temperature range and integrated protection features.

Part Context

This device belongs to the LM1084 series of 5 A low-dropout positive regulators manufactured by Texas Instruments. The series provides both fixed and adjustable output options, designed to replace older standards like the LM317 while offering improved efficiency and lower dropout voltages. The LM1084 family is widely used in applications demanding high current stability and reliable linear regulation.
