The LM2679T-3.3/NOPB is a high-performance, easy-to-use voltage regulator from Texas Instruments, designed for a wide range of applications. This regulator is part of the SIMPLE SWITCHER® family, which is known for its simplicity and robust performance. The LM2679 operates at a switching frequency of 260kHz, allowing for smaller-sized filter components compared to what would be needed with lower-frequency switching regulators.

This particular model, the LM2679T-3.3/NOPB, provides a fixed output voltage of 3.3V, which is a common voltage used in digital circuits. Its ability to deliver up to 3A of continuous output current makes it suitable for powering various devices, from microcontrollers and sensors to more power-hungry components such as DSPs and FPGAs. The output voltage is guaranteed to a ±2% tolerance, ensuring reliable operation for sensitive electronic devices.

The LM2679T-3.3/NOPB comes in a TO-220 package, which is known for its good thermal performance, making it capable of handling higher currents without overheating. This package also allows for easy mounting on printed circuit boards and is suitable for through-hole technology.

Safety and protection features are built into the LM2679T-3.3/NOPB, including thermal shutdown, current limit, and an active output overvoltage protection circuit. These features enhance the reliability and longevity of both the regulator and the end application. Additionally, the regulator has an ON/OFF pin that allows the user to shut down the regulator, reducing the quiescent current to a minimal value when the output is not needed, thereby saving power.

The "NOPB" designation in the part number indicates that this component is lead-free and RoHS compliant, making it an environmentally friendly choice for modern electronic applications. The LM2679T-3.3/NOPB is a versatile, reliable, and efficient solution for a wide array of power supply requirements, solidifying its place in the market as a go-to component for design engineers.
