LM1086IT-ADJ/S5002151

Overview

The LM1086IT-ADJ/S5002151 is a positive adjustable linear voltage regulator from Texas Instruments, housed in a TO-220 package. It delivers up to 1.5A output current with a maximum dropout voltage of 1.5V at full load. The device accepts input voltages ranging from 2.6V to 30V and provides an adjustable output voltage between 1.25V and 27.5V using two external resistors. Key electrical specifications include a typical line regulation of 0.015% and load regulation of 0.1%. It features integrated zener-trimmed band gap reference, current limiting, and thermal shutdown protection for robust operation.

Feature Summary

Provides adjustable positive output voltage via external resistor network
Integrates current limiting and thermal shutdown protection mechanisms
Features low dropout capability with high efficiency under load

Applications

General purpose power supply circuits requiring adjustable regulation
Local voltage regulation for embedded systems and microcontrollers
Battery-powered equipment needing efficient step-down conversion

Procurement Notes

Verify the exact suffix S5002151 against official Texas Instruments documentation to confirm pinout compatibility and functional equivalence with standard LM1086IT-ADJ/NOPB variants. Ensure that the TO-220-3 package dimensions match your thermal management requirements. Confirm that the manufacturer source provides valid traceability for this specific marking code before finalizing procurement orders.

Selection Notes

Select this component when an adjustable LDO with 1.5A capacity is required. It serves as a pin-compatible alternative to the LM317 while offering improved dropout performance. Consider the thermal dissipation capabilities of the TO-220 package relative to the expected load current and ambient temperature conditions to ensure reliable operation within the specified junction temperature limits.

Part Context

This part belongs to the LM1086 family of low-dropout positive regulators manufactured by Texas Instruments. It shares the industry-standard pinout configuration with the LM317, facilitating easy upgrades in existing designs. The series is designed for applications demanding stable regulation with minimal heat generation compared to traditional linear regulators.
