LM3480IM3X-3.3/NOPB

The LM3480IM3X-3.3/NOPB is a low-dropout (LDO) linear voltage regulator designed for applications requiring stable, regulated power supply outputs. This component belongs to the LM3480 family, which is widely used across industrial, consumer electronics, and embedded systems applications where efficient voltage regulation and compact form factors are essential. As a linear regulator, this part functions by taking an input voltage and regulating it to a fixed output voltage, in this case 3.3 volts. The device continuously monitors the output and adjusts its internal pass element to maintain voltage stability despite variations in input voltage or load current changes. This makes it particularly valuable in systems where clean, noise-free power delivery is critical for proper operation of downstream digital or analog circuitry. The IM3X designation indicates this part is housed in a small surface-mount package, making it ideal for modern PCB designs where space efficiency is a priority. The compact package allows engineers to integrate voltage regulation directly near point-of-load applications, minimizing voltage drop and improving overall system efficiency compared to remote regulation architectures. Typical applications for this regulator include microcontroller power supplies, sensor interface circuits, FPGA and DSP auxiliary power rails, wireless communication modules, and various embedded systems requiring 3.3V logic supply voltage. The fixed 3.3V output makes it particularly well-suited for powering modern digital logic families and mixed-signal integrated circuits that have become standard in contemporary electronics. Engineers might select this specific part when they require the combination of a proven LM3480 architecture with the 3.3V output in a surface-mount package. The device offers the reliability and performance characteristics associated with the LM3480 series while accommodating modern automated assembly processes. The NOPB suffix indicates this is a lead-free, RoHS-compliant version, making it compliant with environmental regulations and suitable for applications subject to hazardous substance restrictions. The LM3480 family is valued for straightforward integration, requiring minimal external components for stable operation. This simplicity reduces design complexity and printed circuit board real estate requirements compared to more complex switching regulator topologies, making it an economical choice for applications where the efficiency benefits of switching regulation are not necessary. Whether upgrading legacy designs or developing new systems, this regulator represents a dependable solution for regulated 3.3V power distribution in compact, modern electronic assemblies.
