Overview
The LM1086CT-5.0/NOPB is a positive low-dropout linear regulator manufactured by Texas Instruments, delivering a fixed 5.0V output at up to 1.5A. It operates within an input voltage range of 2.6V to 30V and features a maximum dropout voltage of 1.5V at full load. The device utilizes a TO-220-3 through-hole package with thermal resistance of 23°C/W. It includes internal protection against overcurrent, short circuits, and thermal overload, ensuring reliable operation across a temperature range of 0°C to 125°C.
Feature Summary
- Provides a fixed 5.0V regulated output for stable power supply applications
- Supports continuous load currents up to 1.5A with low dropout characteristics
- Integrates comprehensive protection mechanisms including thermal shutdown and current limiting
Applications
- General-purpose power supplies requiring stable 5V rails
- Battery-powered systems utilizing linear regulation
- Embedded logic and peripheral circuit powering
Procurement Notes
Verify the specific suffix 'CT' confirms the TO-220-3 through-hole package variant rather than surface-mount options. Confirm the 'NOPB' designation indicates lead-free and RoHS compliance status as per manufacturer specifications. Ensure the fixed 5.0V output matches system requirements, as adjustable or other fixed voltage variants exist within the same series.
Selection Notes
Select this component when a robust through-hole solution is required for moderate current loads. The TO-220 package facilitates effective heat dissipation without additional external components. Verify that the input voltage remains within the specified 30V maximum limit and that the dropout voltage accommodates the minimum input-to-output differential under peak load conditions.
Part Context
This part belongs to the LM1086 family of 1.5A low-dropout positive regulators from Texas Instruments. The series offers both fixed and adjustable output configurations in various packages. The LM1086CT-5.0/NOPB specifically provides a fixed 5.0V output in a durable TO-220-3 housing, suitable for industrial and commercial environments requiring high reliability.
