LM1085IT-5.0/NOPB

Overview

The LM1085IT-5.0/NOPB is a 3A low dropout positive linear regulator from Texas Instruments, providing a fixed 5.0V output. It operates with an input voltage range up to 25V and features a maximum quiescent current of 8mA. The device includes internal thermal overload protection and current limiting. It is housed in a TO-220 package and supports junction temperatures up to 125°C.

Feature Summary

Provides stable 3A output current capability for high-power applications
Integrates built-in thermal shutdown and current limit protection mechanisms
Ensures efficient regulation through low dropout voltage characteristics

Applications

Point-of-load regulation in distributed power architectures
Battery-powered systems requiring efficient voltage step-down
General-purpose power supplies needing fixed 5V rails

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS standards as per manufacturer documentation. Confirm the 'IT' prefix corresponds to the specified operating temperature range and package type before ordering. Cross-reference the datasheet revision date to ensure compatibility with current design requirements.

Selection Notes

Select this component when a fixed 5V output at 3A is required with minimal dropout voltage. Ensure the input voltage does not exceed the 25V absolute maximum rating. Consider thermal management solutions due to power dissipation at full load. Compare against adjustable variants if programmable output is needed instead.

Part Context

This part belongs to the LM1085 family of 3A low dropout regulators. It shares functional similarities with the LM1084 and LM1083 series but offers higher current capacity than the LM1084. The NOPB suffix denotes non-lead-based packaging compliant with environmental directives.
