3 InstructionsThe LM2596 series regulators are monolithic integrated circuits that provide all the effective functions of a step-down switching regulator capable of driving 3A loads with excellent line and load regulation. These devices are available in 33V, 5V, 12V fixed output voltage and adjustable output voltage versions. These regulators require few external components and are easy to use, with internal frequency compensation and fixed-frequency oscillators. The LM2596 series operates at a switching frequency of 150kHz, resulting in a smaller filter assembly size than the component required for lower frequency switching regulators. It is available in a standard 5-pin TO-220 package with a variety of different lead bend options, as well as a 5-pin TO-263 surface-mount package.
