LM1086ISX-5.0

Overview

The LM1086ISX-5.0/NOPB is a fixed positive low dropout linear regulator manufactured by Texas Instruments, delivering a maximum output current of 1.5 A with a fixed 5.0 V output voltage. It operates within an input voltage range of 2.6 V to 25 V and features a typical dropout voltage of 1.3 V at full load. The device provides line regulation of 10 mV and load regulation of 20 mV, with a power dissipation rating of 30 W. It includes internal thermal overload and short-circuit protection, operates from -40°C to +125°C, and utilizes a D2PAK-3 (TO-263-3) surface-mount package.

Feature Summary

Fixed 5.0 V output configuration for simplified circuit design
Integrated thermal overload and short-circuit protection mechanisms
Low dropout performance enabling efficient voltage conversion
High power dissipation capability supporting substantial load currents

Applications

Point-of-load regulation in embedded systems
Battery-powered equipment requiring stable voltage rails
General-purpose power supply architectures

Procurement Notes

Verify the complete part number includes the /NOPB suffix to confirm lead-free compliance and specific manufacturer specifications. Confirm the D2PAK-3 package type matches your PCB footprint requirements. Ensure input voltage does not exceed the 25 V maximum limit during operation. Check thermal management needs given the 30 W power dissipation rating under heavy loads.

Selection Notes

Select this component when a fixed 5.0 V rail is required with up to 1.5 A continuous current. The TO-263-3 package offers robust thermal performance compared to smaller SOT packages. Consider the 1.3 V dropout voltage when designing for minimum input-output differentials. 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 variant specifically denotes the surface-mount D2PAK-3 package option. The NOPB suffix indicates a non-pbfree product designation aligned with environmental standards. This series serves as a direct replacement for older National Semiconductor equivalents in existing designs.
