LM1085IT-5.0

Overview

The LM1085IT-5.0 is a 3A low dropout positive linear regulator manufactured by Texas Instruments. It provides a fixed 5.0V output voltage with an input voltage range of 2.6V to 29V. The device features a maximum dropout voltage of 1.5V at full load and operates within a temperature range of -40°C to +125°C. It includes integrated current limiting and thermal shutdown protection. The component is housed in a TO-220-3 through-hole package.

Feature Summary

Provides stable 5.0V fixed output for power supply applications
Supports up to 3A continuous load current capability
Integrates internal current limit and thermal shutdown protection

Applications

Battery chargers
Post-regulators for switching regulators
On-card regulation for microprocessors

Procurement Notes

Verify the manufacturer date code and lot number against the datasheet specifications to ensure authenticity. Confirm that the TO-220-3 package leads are free from damage or oxidation before installation. Check for any specific handling requirements regarding electrostatic discharge during storage and assembly processes.

Selection Notes

Select this component when a fixed 5.0V rail is required with high current capacity. Ensure the input voltage remains within the specified 2.6V to 29V range. Consider the thermal dissipation capabilities of the TO-220 package relative to the expected ambient temperature and load conditions.

Part Context

This part belongs to the LM1085 series of low dropout positive regulators. It shares pinout compatibility with industry-standard adjustable regulators like the LM317, facilitating design flexibility. The series offers various fixed voltage options and adjustable versions for diverse power management needs.
