The LM negative complement to the LM regulates voltages below, rather than above, the reference.

Accidenti come scotta questo transistor. Page 27 Notes 27 www. The output current is that resulting from dropping the reference voltage across the resistor. The alternative is to use a switching voltage regulator which is usually more efficient but has a larger footprint and requires datashete larger number of associated components.

Datassheet Pins datashset Output Current 1. In use an LM commonly requires a heat sink to prevent the operating temperature rising too high. In packages with a heat-dissipating mounting tab, such as TOthe 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.

This page was last edited on 6 Julyat Because some quiescent current flows from the adjustment pin of the device, an error term is added:.

Because of this, the error term in the formula cannot be ignored and the value of the low-side resistor becomes more critical. All other trademarks are the property of their respective owners. Failure to do this may cause the circuit to short.
