LM3480IM3-5.0/NOPB

The LM3480IM3-5.0/NOPB is a fixed-output linear voltage regulator manufactured by Texas Instruments. This component is designed to deliver a regulated 5.0-volt output from an unregulated input source, making it suitable for powering low-voltage logic circuits, microcontroller systems, and other 5V-dependent electronics in industrial and embedded applications. As a member of the LM348x regulator family, this part functions as a positive linear regulator that maintains stable output voltage despite variations in input voltage or load current demands. Linear regulators like this one are widely used in applications where simple voltage conversion, noise filtering, and circuit protection are required without the complexity of switching-mode power supplies. This makes them particularly valuable in legacy systems, analog circuits, and noise-sensitive applications where electromagnetic interference must be minimized. The IM3 package designation indicates this component comes in a small surface-mount package format, specifically a 3-pin configuration. Surface-mount packaging is preferred in modern PCB designs because it reduces board space requirements, improves thermal characteristics through better board coupling, and facilitates automated manufacturing processes. The NOPB suffix indicates this is a lead-free product variant, meeting environmental and compliance requirements for industrial and commercial markets. Engineers typically specify the LM3480IM3-5.0/NOPB when they need a compact, straightforward solution for 5-volt regulation in space-constrained designs. Its fixed 5.0-volt output eliminates the need for external feedback networks, reducing component count and design complexity compared to adjustable regulators. This makes it an economical choice for high-volume production where simplicity and reliability are priorities. The regulator includes integrated current-limiting and thermal-shutdown protection, safeguarding against short-circuit conditions and overtemperature scenarios. These protective features make it suitable for applications where robustness and fail-safe operation are important, such as industrial controllers, measurement equipment, and telecommunications hardware. Typical applications include powering digital logic in data acquisition systems, providing clean 5V rails for sensor interfaces, supplying reference voltages for analog circuits, and delivering stable power to communication modules and microcontroller subsystems. The small footprint and fixed output make this regulator ideal for confined spaces in industrial electronics where multiple low-voltage supplies are needed on a single board. Engineers choosing this specific part value benefit from its simplicity, proven reliability, standardized performance characteristics within the LM348x family, and widespread availability through industrial component distributors.
