LM1084IS-5.0/NOPB

Overview

The LM1084IS-5.0/NOPB is a fixed-output low dropout positive regulator manufactured by Texas Instruments, delivering a stable 5V output at up to 5A load current. Housed in a D2PAK-3 (TO-263-3) surface-mount package, it operates within an input voltage range of 2.6V to 25V. The device features a maximum dropout voltage of 1.5V at full load and includes internal thermal shutdown and current limiting protections. It supports industrial temperature ranges from -40°C to +125°C with a typical power dissipation capacity of 30W.

Feature Summary

Integrated fixed 5.0V output eliminates external resistor requirements for standard regulation applications
Low dropout architecture maintains regulation with minimal input-to-output voltage differential under heavy loads
Built-in thermal shutdown and current limit protection ensure device safety during overload or high-temperature conditions

Applications

Post-regulation stage for switching DC/DC converters to reduce ripple
Battery-powered systems requiring efficient linear regulation
General-purpose power supplies for embedded electronics

Procurement Notes

Verify the complete part number including the NOPB suffix to confirm lead-free and RoHS compliance status. Confirm the TO-263-3 package variant matches your PCB footprint requirements. Check manufacturer datasheets for specific humidity sensitivity levels and storage handling instructions prior to assembly.

Selection Notes

Select this component when a fixed 5V rail is required with high current capability in a compact surface-mount form factor. Ensure the input voltage remains within the 25V maximum limit and consider thermal management strategies due to significant power dissipation at high load currents compared to lower-current alternatives.

Part Context

This device belongs to the LM1084 family of 5A low dropout regulators produced by Texas Instruments. It serves as a robust solution for medium-power linear regulation tasks where efficiency and simplicity are prioritized over ultra-low noise performance. The series offers both adjustable and fixed voltage options across various packages.
