In packages with a heat-dissipating mounting tab, such as TOthe tab is connected internally lm371at the output pin which may make it necessary to electrically isolate the tab or the heat sink from other parts of the application circuit.

LMAT Datasheet pdf – 3-Terminal Adjustable Regulator – National Semiconductor
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.
Besides replacing fixed regulators, the LM is useful in a. Linear regulators inherently waste power, the power dissipated is the current passed multiplied by the voltage difference between input and output.
Elcodis is a trademark of Elcodis Company Ltd. Because of this, the error term in the formula cannot be ignored and the value of the low-side resistor becomes more critical. Higher regulated voltages are obtained by connecting the adjustment pin to a resistive voltage divider between the output and dafasheet. Output capacitors in the range. An optional output ca.

In addition to higher performance than fixed regulators, the. If the adjustment pin is connected to ground the output pin delivers a regulated voltage of 1.
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 vatasheet for V ref e. They are exceptionally easy to use. However, the 78xx device’s quiescent current is substantially higher and less stable.

Page 17 Regulator Full output current not available at high input-output voltages High Current Adjustable Regulator 17 Power Follower www. LMAT datasheet and specification datasheet Download datasheet. The LM is an adjustable analogue to the popular 78xx fixed regulators. The output current is that resulting from dropping the reference voltage across the resistor.
LM series offers full overload protection available only in. 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.
How the adjustment pin is connected determines the output voltage as follows. Maximum Allowable Power Dissipation vs. Datasheeh 12 Layout Top Side Note: The LM is a popular adjustable positive linear voltage regulator.
Page 18 Current Regulator 1. The LM negative complement to the LM regulates voltages below, rather than above, the reference. It was designed by Robert “Bob” Pease. Also, the LM is packaged in.
