LM1086IT-ADJ/NOPB

Overview

The LM1086IT-ADJ/NOPB is a positive low dropout linear regulator manufactured by Texas Instruments. It provides an adjustable output voltage ranging from 1.25V to 27.5V with a maximum load current of 1.5A. The device accepts input voltages between 2.6V and 30V. It features a typical dropout voltage of 1.3V at full load, with a maximum of 1.5V. The unit operates within a temperature range of -40°C to +125°C and utilizes a TO-220-3 through-hole package.

Feature Summary

Compatible pinout with industry standard LM317 for easy design migration
Integrated zener-trimmed band gap reference for accurate regulation
Built-in thermal shutdown and current limiting protection mechanisms

Applications

General purpose power supply regulation
Local voltage regulation in embedded systems
Battery-powered equipment requiring efficient step-down conversion

Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status as per manufacturer specifications. Confirm the 'IT' suffix indicates the correct temperature grade and package variant for your assembly process. Cross-reference the datasheet revision date to ensure all electrical characteristics match your design requirements before finalizing procurement orders.

Selection Notes

Select this component when a 1.5A current capacity is required with an adjustable output voltage. Ensure the input voltage remains within the specified 2.6V to 30V range. Consider the thermal performance in the TO-220 package if operating near maximum current limits. Verify that the application does not require ceramic output capacitors without additional stability measures, as recommended in the official documentation.

Part Context

This part belongs to the LM1086 family of low dropout regulators from Texas Instruments. It serves as a direct pin-compatible alternative to the LM317, offering improved efficiency and lower dropout voltage. The family includes fixed voltage variants and different package options such as D2PAK and WSON, catering to various power management needs in industrial and consumer electronics.
