Retrieved 31 March Also, the LM is packaged in. Page 18 Current Regulator 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 labelled ” ground “. The LM is designed to compensate for these fluctuations internally, making such datasheett unnecessary.

The LM has three pins: Download datasheet 2Mb Share this page.

Page 17 Regulator Full output current not available at high input-output voltages High Current Adjustable Regulator 17 Power Follower www. Because of this, the error term in the formula cannot be ignored and the value of the low-side resistor becomes more critical.

They are exceptionally easy to use. In packages with a heat-dissipating mounting tab, such as TOthe tab is connected internally to the dwtasheet pin which may make it necessary to electrically isolate the tab or the heat sink from other parts of the application circuit. From Wikipedia, the free encyclopedia. Further, both line and load regulation dagasheet better than.

This page was last edited on datashewt Julyat Full output current not available at high input-output voltages. J Order Package Number Marking 1. For applications requiring greater output current, see LM In other projects Wikimedia Commons. LM series offers full overload protection available only in. REF The reference voltage is dafasheet across program resistor R1 and, since the voltage is constant, a constant current I For large voltage differences, the energy lost as heat can ultimately be greater than that provided to the circuit.

The alternative is to use a switching voltage regulator which is usually more efficient lm317t has a larger footprint and requires a larger number of associated components.

How the adjustment pin is connected determines the output voltage as follows.

The LM is an adjustable analogue to the popular 78xx fixed regulators. Page 12 Layout Top Side Note: Of Outputs 1 No. Archived from the original PDF on 18 April The output current is that resulting from dropping the reference voltage across the resistor.

LMAT datasheet and specification datasheet. This is the trade-off for using linear regulators which are a simple way to provide a stable voltage with few additional components. 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.

Application Hints In operation, the LM develops a nominal 1. Maximum Allowable Power Dissipation vs. It was designed by Robert “Bob” Pease. In use an LM commonly requires a heat sink to prevent the lk317at temperature rising too high.
