The LM has three pins: For more National Semiconductor product information and proven design tools, visit the following Web sites at: 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.
Maximum Allowable Power Dissipation vs. Page 17 Regulator Full output current not available at high input-output voltages High Current Adjustable Regulator 17 Power Follower www.
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.

Normally, no capacitors are needed unless the device is sit. How the adjustment pin is connected determines the output voltage as follows. LMAT datasheet and specification datasheet. Copy your embed code and put on your site: Archived from the original PDF on 18 April It was designed by Robert “Bob” Pease.
If the adjustment pin is connected to ground the output pin delivers a regulated voltage of 1. Archived from the original PDF on 31 March LM can be used as a precision current regulator.

Further, both line and load regulation are better than. Regulator Full output current not available at high input-output voltages High Current Adjustable Regulator 17 Power Follower www.
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.
J Order Package Number Marking 1. Linear integrated circuits Voltage regulation. The LM is a popular adjustable positive linear voltage regulator. Download datasheet 2Mb Share this page.
Wikimedia Commons has media related to LM and Voltage regulator circuits. They are exceptionally easy to use. Application Hints In operation, the LM develops a nominal 1. Besides replacing fixed regulators, the LM is useful in a. LMAT datasheet and specification datasheet Download datasheet. 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.
