LM317

From Wikipedia, the free encyclopedia

LM317 is an integrated three-terminal adjustable linear voltage regulator. It supports input voltage of 3V to 40V and output voltage between 1.25V and 37V. It has a current rating of at least 1.5A although lower current models are available. Its output voltage is controlled by a resistor or a potentiometer. The LM317 also has a built-in current limiter as a safety feature. LM317 is manufactured by many companies, including National Semiconductors and Fairchild Semiconductor. The LM317 will automatically reduce output current if it gets too hot. See the application notes for important information on heatsinking, bypassing, and other important points.
