The output current is that resulting from dropping the reference voltage across the resistor. Download datasheet 2Mb Share this page. The LM negative complement to the LM regulates voltages below, rather than above, the reference. The LM relates in the same way to the fixed 79xx regulators.

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 a popular adjustable positive linear voltage regulator. Because some quiescent current flows from the adjustment pin of the device, lm371at error term is added:.


Also, the LM is packaged in. How the adjustment pin is connected determines the output voltage as follows.

They are exceptionally easy to use. Output capacitors in the range.

Page 18 Current Regulator 1. Elcodis is a trademark of Elcodis Company Ltd. The LM is an adjustable analogue to the popular 78xx fixed regulators. Copy your embed code and put on your site: Failure to do this may cause the circuit to short.

In use an LM commonly requires a heat sink to prevent the operating temperature rising too high. Page 27 Notes 27 www. Archived from the original PDF on 18 April Layout Top Side Note: 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.

Retrieved from ” https: The LM series of adjustable 3-terminal positive voltage. Besides replacing fixed regulators, the LM is useful in a.

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. Page 8 Line Transient Response www.

However, the 78xx device’s quiescent current is substantially higher and less stable. Archived from the original on 17 December Included on the chip are current limit, thermal overload.
