Floating Operation for High Voltage Applications 7. 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 of Use and Privacy Policy. Output Current in Excess of 1. Output Transistor Safe—Area Compensation 6.

The LM is a popular adjustable positive linear voltage regulator. The LM is an adjustable analogue to the popular 78xx fixed regulators. Output Adjustable between 1.

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 TOthe tab is connected internally to the output pin which may make it necessary to electrically datwsheet the tab or the heat sink from other parts of the application circuit.

Linear regulators inherently waste power, the power dissipated is the current passed multiplied by the voltage difference between input and xatasheet. 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. Because some quiescent current datasgeet from the adjustment pin of the device, an error term is added:.

From Wikipedia, the free encyclopedia.

Archived from the original PDF on 18 April Wikimedia Commons has media related to LM and Voltage regulator circuits. The LM relates in the same way to the fixed 79xx regulators.

This datashedt was last edited on 6 Julyat This is the trade-off for using linear regulators which are a simple way to provide a stable voltage with few additional components. Because of this, the error term in the formula cannot be ignored and the value of the low-side resistor becomes more critical.

Archived from the original PDF on 31 March Further, it employs internal current limiting, thermal shutdown and safe area compensation, making it essentially blow—out proof. In other projects Wikimedia Commons. How the adjustment pin is dtasheet determines the output voltage as follows.

Three Terminal Positive Voltage Regulator. Retrieved from ” https: Views Read Edit View history. Accidenti come scotta questo transistor.

Three-terminal adjustible output positive voltage regulator. Higher regulated voltages are obtained by connecting the adjustment pin to a resistive voltage divider between the output and ground.

Failure to do this may cause the circuit to lm317by. Linear integrated circuits Voltage regulation.

It was designed by Robert “Bob” Pease. Three-Terminal Positive Voltage Regulator. The LM is an adjustable 3—terminal positive voltage regulator capable of supplying in excess of 1. The LM negative complement to the LM regulates voltages below, rather than above, the reference. However, the 78xx device’s quiescent current is substantially higher and less stable. Three-terminal positive voltage regulator. Eliminates Stocking many Fixed Voltages.

In use an LM datasneet requires a heat sink to prevent the operating dtasheet rising too high. 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.

The LM has three pins: The LM is designed to compensate for daasheet fluctuations internally, making such measures unnecessary. Internal Thermal Overload Protection 4. This voltage regulator is exceptionally easy to use and requires only two external resistors to set the output voltage. The output current is that resulting from dropping the reference voltage across the resistor. For large voltage differences, the energy lost as heat can ultimately be greater than that provided to the circuit.

1.5 A Adjustable Output, Positive Voltage Regulator

The LM serves a wide variety of applications including local, on card regulation. If the adjustment pin is connected to ground the output pin delivers a regulated voltage of 1. Like the LM, each of the 78xx regulators is designed to adjust the output voltage until it is some fixed voltage above the adjustment pin which in this case is dztasheet ” ground “.
