LM1086ISX-5.0/NOPB

Overview

The LM1086ISX-5.0/NOPB is a fixed-output positive low dropout linear regulator manufactured by Texas Instruments. It provides a regulated 5.0 V output with a maximum continuous current of 1.5 A. The device utilizes a D2PAK-3 (TO-263-3) surface-mount package and supports an input voltage range from 2.6 V to 29 V. Key electrical specifications include a typical dropout voltage of 1.3 V at full load, a quiescent current of approximately 10 mA, and a line regulation of 10 mV. It operates reliably within a temperature range of -40°C to +125°C.

Feature Summary

Fixed 5.0 V output configuration for simplified circuit design
Integrated thermal overload and short-circuit protection mechanisms
Low dropout characteristic enabling efficient operation with minimal input-output differential

Applications

Point-of-load regulation in embedded systems
Battery-powered equipment requiring stable 5 V supply
General-purpose power management in industrial control units

Procurement Notes

Verify the complete part number including the suffix /NOPB to confirm lead-free compliance and specific manufacturer revisions. Confirm the TO-263-3 package variant matches your PCB footprint requirements. Ensure input voltage does not exceed the absolute maximum rating of 29 V under all operating conditions. Check thermal dissipation capabilities based on expected ambient temperatures and load currents.

Selection Notes

Select this component when a fixed 5 V output is required with up to 1.5 A capacity. The TO-263-3 package offers improved thermal performance compared to smaller SOT packages. Consider the 1.3 V dropout voltage when determining minimum input voltage requirements. Verify that the application environment stays within the specified -40°C to +125°C operating temperature range.

Part Context

This device belongs to the LM1086 family of 1.5 A low dropout positive regulators. The ISX designation indicates a surface-mount version in the TO-263-3 package. The /NOPB suffix denotes a non-pb-free or lead-free compliant variant depending on specific manufacturing updates. This series is designed for applications requiring high efficiency and robust protection features.
