LM317M DATASHEET PDF

Linear regulators inherently waste power; the power dissipated is the current passed multiplied by the voltage difference between input and output. A LM commonly requires a heat sink to prevent the operating temperature from rising too high. For large voltage differences, the power lost as heat can ultimately be greater than that provided to the circuit. This is the tradeoff for using linear regulators, which are a simple way to provide a stable voltage with few additional components. The alternative is to use a switching voltage regulator , which is usually more efficient, but has a larger footprint and requires a larger number of associated components. In packages with a heat-dissipating mounting tab, such as TO , the tab is connected internally to the output pin which may make it necessary to electrically isolate the tab or the heat sink from other parts of the application circuit.
