The LM2576 available in fixed output voltages of 3.3V, 5V, 012Vand an adjustable output version.<\/p>\n\n\n\n<p>Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation and a fixed-frequency oscillator.<\/p>\n\n\n\n<p>The LM2576 series offers a high-efficiency replacement for popular three-terminal linear regulators. It substantially reduces the size of the heat sink, and in some cases no heat sink is required. A standard series of inductors optimized for use with the LM2576 are available from several different manufacturers. This feature greatly simplifies the design of switch-mode power supplies.<\/p>\n\n\n\n<p>Other features include a guaranteed \u00b14% tolerance on output voltage within specified input voltages and output load conditions, and \u00b110% on the oscillator frequency. External shutdown is included, featuring 50 \u00b5A (typical) standby current. The output switch includes cycle-by-cycle current limiting, as well as thermal shutdown for full protection under fault conditions.<\/p>\n\n\n\n<p>The LM2576 is available in TO-220T-5L and TO-263-5L package.<\/p>\n<\/div><\/div>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-4 is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure
