Description
The National Semiconductor LM2576SX-5.0/NOPB is a voltage regulator. It is designed to provide a constant output voltage of 5 volts. The device is capable of delivering up to 3 amps of current and can operate with an input voltage ranging from 7.5 to 40 volts. It uses a simple switcher topology to regulate the output voltage and is highly efficient, with a typical efficiency of 80%. The device is also protected against over-temperature, over-current, and short-circuit conditions, providing added reliability and safety.
The LM2576SX-5.0/NOPB is housed in a small eight-pin SOIC package, making it an ideal choice for applications where space is at a premium. The package includes a heat sink pad for improved thermal performance, allowing the device to operate in a wide range of ambient temperatures. The output voltage is set using an external resistor, allowing for flexibility in design. The device is frequently used in automotive, industrial, and telecommunications applications, where a stable, reliable power supply is critical. Its low cost and ease of use make it a popular choice for both hobbyists and professional designers alike
