It was designed by Robert “Bob” Pease. The output current is that resulting from dropping the reference voltage across the resistor. Archived from the original PDF on 31 March An optional output ca. Full output current not available at high input-output voltages.

Also, the LM is packaged in. The LM relates in the same way to the fixed 79xx regulators. Maximum Allowable Power Dissipation vs. Linear integrated circuits Voltage regulation. Of Pins 3 Output Current 1. The LM is an adjustable analogue to the popular 78xx fixed regulators.

This page was last edited on 6 Julyat LMAT datasheet and specification datasheet Download datasheet. J Order Package Number Marking 1. Page 17 Regulator Full output current not available at high input-output voltages High Current Adjustable Regulator 17 Power Follower www.

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

Further, both line and load regulation are better than. LM series offers full overload protection available only in. In other projects Wikimedia Commons. However, the 78xx device’s quiescent current is substantially higher and less stable. The LM has three pins: Lm3117at from the original on 17 December Higher regulated voltages are obtained by connecting the adjustment pin to a resistive voltage divider between the output and ground.

Views Read Edit View history. Page 12 Layout Top Side Note: The LM negative complement to the LM regulates voltages below, rather than above, the reference. The LM series of adjustable 3-terminal positive voltage.

They are exceptionally easy to use. LM can be used as a precision current regulator. Page 18 Current Regulator 1. Wikimedia Commons has media related to LM and Voltage regulator circuits. Retrieved from ” https: Included on the chip are current limit, thermal overload. Besides replacing fixed regulators, the LM is useful in a. In use an LM commonly requires a heat sink to datasheef the operating temperature rising too high. Because some quiescent current flows from the adjustment pin datashedt the device, an error term is added:.

Also, it makes an especially simple adjustable switching reg. For applications requiring greater output current, see LM For large voltage differences, the energy lost as heat can ultimately be greater than that provided to the circuit.

Output capacitors in the range. All other trademarks are the property of their respective owners. The LM is a popular adjustable positive linear voltage regulator.

Page 8 Line Transient Response www. Download datasheet 2Mb Share this page. Normally, no capacitors are needed unless the device is sit. Failure to do this may cause the circuit to short. Copy your embed code and put on your site: 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 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 datasheeh formula, using the regulator’s fixed voltage for V ref e.

REF The reference voltage is impressed across program resistor R1 and, since the voltage is constant, a constant current I Of Outputs 1 No.
