Copy your embed code and put on your site: The LM is a popular adjustable positive linear voltage regulator. For guaranteed specifications and test conditions, see the Datasheett Characteristics.

Application Hints In operation, the LM develops a nominal 1. From Wikipedia, the free encyclopedia. Page 27 Notes 27 www. 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. Archived from the original on xatasheet December Normally, no capacitors are needed unless the device is sit.

Included on the chip are current limit, thermal overload.

This is the trade-off for using linear regulators which are a simple way to provide a stable voltage with few additional 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 isolate the tab or the heat sink from other parts of the application circuit. How the adjustment pin is connected determines the output voltage as follows. Regulator Full output current datahseet available at high input-output voltages High Current Adjustable Regulator 17 Power Follower www.

The output current is that resulting from dropping the reference voltage across the resistor.

REF The reference voltage is impressed across program resistor R1 and, since the voltage is constant, a constant current I The LM series of adjustable 3-terminal positive voltage. For large voltage differences, the l1m17h lost as heat can ultimately be greater than that provided to the circuit.

Because of this, the error term in the formula cannot be ignored and the value of the low-side resistor becomes more critical.

In addition to higher performance than fixed regulators, the. Also, the LM is packaged in. Prev Next 3-Terminal Adjustable Regulator. They are exceptionally easy to datwsheet.

The LM negative complement to the LM regulates voltages below, rather than above, the reference. 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 labelled ” ground “.
