Output Current in Excess of 1. Views Read Edit View history. Higher regulated voltages are obtained by connecting the adjustment pin to a resistive voltage divider between the output and ground. This is the trade-off for using linear regulators which are a simple way to provide a stable voltage with few additional components. The LM is designed to compensate for these fluctuations internally, making such measures unnecessary. Three-terminal adjustible output positive voltage regulator.

In other projects Wikimedia Commons. The device can be configured to regulate the current to a load, rather than the voltage, by replacing the low-side resistor of the divider with the load itself. Wikimedia Commons has media related to LM and Voltage regulator circuits.

The LM serves a wide variety of applications including local, on card regulation. Further, it employs internal current limiting, thermal shutdown and safe area compensation, lm317bf it essentially blow—out proof.


Failure to do this may cause the circuit to short. From Wikipedia, the free encyclopedia. Archived from the original on 17 December The LM is a popular adjustable positive linear voltage regulator. By using this site, you agree to the Terms of Use and Privacy Policy. This voltage regulator is exceptionally easy to use and requires only two external resistors to set the output voltage. However, the 78xx device’s quiescent current is substantially higher and less stable.

The LM negative complement to the LM regulates voltages below, rather than above, the reference. How the adjustment pin is connected datashewt the output voltage as follows. It was designed by Robert “Bob” Pease.

Three-terminal positive voltage regulator. This page was last edited on 6 Julyat The output current is that resulting from dropping the reference voltage across the resistor. Linear integrated circuits Voltage regulation.

Output Adjustable between 1. Output Transistor Safe—Area Compensation 6. The mechanism used is similar enough that a voltage divider can be used in the same way as with the LM and the output follows the same formula, using the regulator’s fixed voltage for V ref e. The LM relates in the same way to the fixed 79xx regulators. In use an LM commonly requires a heat sink to prevent the operating temperature rising too high.


Linear regulators inherently waste power, the power dissipated is the current passed multiplied by the voltage difference between input and output. Three-Terminal Positive Voltage Regulator. The LM is an adjustable 3—terminal positive voltage regulator capable of supplying in excess of 1.

Because some quiescent current flows from the adjustment pin of the device, an error term is added:. Retrieved from ” https: If the adjustment pin is connected to ground the datashest pin delivers a regulated voltage of 1.

Three Terminal Positive Voltage Regulator.

Retrieved 31 March The LM has three pins: 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 datasheeg other parts of the application circuit.
