LM1086ILDX-ADJ/NOPB

Overview

The LM1086ILDX-ADJ/NOPB is a positive adjustable low-dropout linear regulator manufactured by Texas Instruments. It provides an output current capability of 1.5 A with a maximum input voltage rating of 30 V. The device features a fixed reference voltage of 1.25 V and operates within a junction temperature range of -40°C to +125°C. It utilizes an LLP-8 surface-mount package and incorporates internal thermal overload and current limit protection circuits.

Feature Summary

• Adjustable output voltage configuration via external resistor divider
• Integrated thermal shutdown and current limiting protection mechanisms

Applications

• Point-of-load regulation for embedded systems
• Battery-powered equipment requiring efficient step-down conversion
• General-purpose power supply architectures

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout compatibility and electrical tolerances. Ensure the procurement channel sources genuine components from authorized distributors to prevent counterfeit infiltration. Cross-reference the date code and lot number with the manufacturer's traceability records to validate authenticity and storage history prior to integration into production lines.

Selection Notes

Select this component when a 1.5 A output current is required in a compact surface-mount footprint. The adjustable output feature allows flexibility for various voltage rails compared to fixed versions. Consider the thermal performance requirements of the LLP-8 package relative to the expected ambient operating conditions and PCB copper area available for heat dissipation during high-load scenarios.

Part Context

This part belongs to the LM1086 family of low-dropout regulators, designed for applications requiring moderate current capabilities. The LLP-8 package variant offers a smaller board space solution compared to traditional through-hole or larger surface-mount packages like TO-263, facilitating denser circuit board layouts while maintaining robust regulatory performance characteristics.
