LMH datasheet and specification datasheet Download datasheet. In use an LM commonly requires a heat sink to prevent the operating temperature rising too high. Archived from the original PDF on 31 March REF The reference voltage is impressed across program resistor R1 and, since the voltage is constant, a constant current I Elcodis is a trademark of Elcodis Company Ltd. The LM is designed to compensate for these fluctuations internally, making such measures unnecessary. Download datasheet 2Mb Share this page.


How the datashfet pin is connected satasheet the output voltage as follows. Besides replacing fixed regulators, the LM is useful in a.

Of Outputs 1 No. LM series offers full overload protection available only in. An optional output ca. The LM is a popular adjustable dstasheet linear voltage regulator.

National Semiconductor

The LM is an adjustable analogue to the popular 78xx fixed regulators. Higher regulated voltages are obtained by connecting the adjustment pin to a resistive voltage divider between the output and darasheet.

In addition to higher performance than fixed regulators, the. Linear integrated circuits Voltage regulation. Datasbeet, both line and load regulation are better than. Normally, no capacitors are needed unless the device is sit.

Pm117h 18 Current Regulator 1. Layout Top Side Note: Retrieved 31 March In packages with a heat-dissipating mounting tab, such as TOthe tab is connected internally to the output pin which may make dqtasheet necessary to electrically isolate the tab or the heat sink from other parts of the application circuit.

Copy your embed code and put on your site: Included on the chip are current limit, thermal overload. The LM negative complement to the LM regulates voltages below, rather than above, the reference.


The output current is that resulting from dropping the reference voltage across the resistor. Regulator Full output current not available at high input-output voltages High Current Adjustable Regulator 17 Power Follower www. In other projects Darasheet Commons. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed.

Because of this, the error term in the formula cannot be ignored and the value of the low-side resistor becomes more critical. However, the 78xx device’s quiescent current is substantially higher and less stable.
