Three-terminal adjustible output positive voltage regulator. Like dataeheet 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 labelled ” ground “.

In other projects Wikimedia Commons. Archived from the original on 17 December 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. It was designed by Robert “Bob” Pease. However, the 78xx device’s quiescent current is substantially higher and less stable.

Because some quiescent current flows from the adjustment darasheet of the device, an error term is added:. This page was last edited on 6 Julyat The LM is an adjustable analogue to the popular 78xx datasheeh regulators. Output Adjustable between 1. The LM negative complement to the LM regulates voltages below, rather than above, the reference.

Failure to do this may cause the circuit to short. Retrieved 31 March Archived from the original PDF on 31 March Three-terminal positive voltage regulator.

For large voltage differences, the energy lost as heat can ultimately be greater than that provided to the circuit. Floating Operation for High Voltage Applications 7. Output Current in Excess of 1. How the adjustment pin is datashet determines the output voltage as follows.

Eliminates Stocking many Fixed Voltages. The LM is a popular adjustable positive linear voltage regulator. The LM serves a wide variety of applications including local, on card regulation. This is the trade-off datashheet using linear regulators which are a simple way to provide a stable voltage with few additional components. Three Terminal Positive Voltage Regulator.

Views Read Edit View history. Further, it employs internal current limiting, thermal shutdown and safe area compensation, making it essentially blow—out proof. Higher regulated voltages are obtained by connecting the adjustment pin to a resistive voltage divider between the output and ground. 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.

The LM relates in the same way to the fixed 79xx regulators. The mechanism used is similar enough that a datashset 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.

Output Transistor Safe—Area Compensation 6.

In use an LM commonly requires a heat sink to prevent the operating temperature rising too high. Linear integrated circuits Voltage regulation. The LM is an adjustable 3—terminal positive voltage regulator capable of supplying in excess of 1. The LM has three datashset From Wikipedia, the free encyclopedia. If the adjustment pin is connected to ground the output pin delivers a regulated voltage of 1. Linear regulators inherently waste datashee, the power dissipated is the current passed multiplied by the voltage difference between input and output.

This voltage regulator is exceptionally easy to use datashet requires only two external resistors to set the output voltage. 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 output current is that resulting from dropping the reference voltage across the resistor. Archived from the original PDF on 18 April
