LM1086IS-5.0

Overview

The LM1086IS-5.0/NOPB is a fixed positive low dropout linear regulator manufactured by Texas Instruments, delivering a stable 5.0 V output with a maximum continuous current of 1.5 A. Housed in a D2PAK (TO-263) surface-mount package, this device supports input voltages up to 30 V and operates within an extended temperature range from -40 °C to +125 °C. It features a typical dropout voltage of 1.3 V at full load and includes internal thermal overload and short-circuit protection mechanisms.

Feature Summary

Integrated thermal overload and short-circuit protection for enhanced reliability
Low dropout voltage characteristic enabling efficient power conversion
Fixed 5.0 V output option eliminating external resistor networks

Applications

General-purpose 5 V power supply circuits
Battery-powered equipment requiring efficient voltage regulation
Embedded systems and microcontroller power rails

Procurement Notes

Verify the specific suffix designation when ordering, as the base model number may refer to adjustable variants or different packages. Confirm RoHS compliance status via the official datasheet, as historical versions may differ. Ensure the procurement channel provides genuine components from authorized distributors to avoid counterfeit devices. Cross-reference the exact part number against the manufacturer's latest release notes to confirm availability and lifecycle status.

Selection Notes

Select this component when a fixed 5.0 V rail is required with high current capability up to 1.5 A. The TO-263 package offers superior thermal dissipation compared to smaller SMD options, making it suitable for applications with moderate heat generation. Consider the minimum input voltage requirement relative to the expected load conditions to ensure adequate headroom for proper regulation without excessive power loss.

Part Context

This device belongs to the LM1086 family of 1.5 A low dropout positive regulators. The series includes both fixed voltage outputs and adjustable versions, available in various packages such as TO-220 and WSON. The LM1086IS-5.0 specifically targets applications needing a robust, cost-effective solution for stepping down higher voltages to a standard 5 V logic level.
