The LM is a popular adjustable positive linear voltage regulator.

Further, it employs internal current limiting, thermal shutdown and safe area compensation, making it essentially blow—out proof. Archived from the original PDF on 18 April If the adjustment pin is connected to ground the output pin delivers a regulated voltage of 1.

The LM is designed to compensate for these fluctuations internally, making such measures unnecessary.

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.

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. By using this site, you agree to the Terms datashert Use and Privacy Policy.

Because of this, the error term in the formula cannot be ignored and the value of the low-side resistor becomes more critical. Retrieved from ” https: The alternative is to lm3177bt a switching voltage regulator which is usually more efficient but has a larger footprint and requires a larger number of associated components.

Retrieved 31 March Failure to do this may cause the circuit to short.

This page was last edited on 6 Julyat The output current is that resulting from dropping the reference voltage across the resistor. The LM is an adjustable 3—terminal positive voltage regulator capable of supplying in excess of 1. This device can also be used to make a programmable output regulator, or by connecting a fixed resistor between the adjustment and output, the LM can be used as a precision current regulator.

Output Transistor Safe—Area Compensation 6.

It was designed by Robert “Bob” Pease. Linear integrated circuits Voltage regulation. Archived from the original on 17 December However, the 78xx device’s quiescent current is substantially higher and less stable.

Three-Terminal Positive Voltage Regulator. The LM negative complement to the LM regulates voltages below, rather than above, the reference.

Eliminates Stocking many Fixed Voltages. The LM has three pins: Internal Thermal Overload Protection 4.

In other projects Wikimedia Commons. Floating Operation for High Voltage Applications 7. 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. Archived from km317bt original PDF on 31 March For large lm31bt differences, the energy lost as heat can ultimately be greater than that provided to the circuit.

Three-terminal adjustible output positive voltage regulator. How the adjustment pin is connected determines the output voltage as follows. 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 datsaheet regulator’s fixed voltage for V ref e.
