The LM2596 series of regulators are monolithic integrated circuits that deliver all the active functions needed for a step-down (buck) switching regulator. This versatile regulator is capable of driving a 3-A load with excellent line and load regulation. The LM2596 provides an efficient, reliable, and adjustable DC-DC constant current/voltage conversion, making it ideal for a wide range of applications including power supply designs and other electronic projects requiring a regulated output voltage.
