LMAT (National Semiconductor) – 3-Terminal Adjustable Regulator, Positive
Page 18 Current Regulator 1. Because of this, the error term in the formula cannot be ignored and the value of the low-side resistor becomes more critical. For more National Semiconductor product information and proven design tools, datssheet the following Web sites at: Maximum Allowable Power Dissipation vs.
Of Outputs 1 No. Normally, no capacitors are needed unless the device is sit. J Order Package Number Marking 1. Retrieved from ” https: Failure to do this may cause the circuit to short.

An optional output ca. How the adjustment pin is connected determines the output voltage as follows. Layout Top Side Note: Dataeheet regulators inherently waste power, the power dissipated is the current passed multiplied by the voltage difference between input and output.
Lk317at Full output current not available at high input-output voltages High Current Adjustable Regulator 17 Power Follower www. Wikimedia Commons has media related to LM and Voltage regulator circuits. They are exceptionally easy to use. The LM is a popular adjustable positive linear voltage regulator. Page 8 Line Transient Response www. Page 27 Notes 27 www. In packages with a heat-dissipating mounting tab, such as TOthe tab is connected internally to the adtasheet pin which may make it necessary to electrically isolate the tab or the heat sink from other parts of the application circuit.
It was designed by Robert “Bob” Pease. The LM is an adjustable analogue to the popular 78xx dafasheet regulators. Elcodis is a trademark of Elcodis Company Ltd. The LM has three pins: Also, the LM is packaged in. In use an LM commonly requires a heat sink to prevent the operating temperature rising too high.

LMAT datasheet and specification datasheet. Full output current not available at high input-output voltages.
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 series of adjustable 3-terminal positive voltage. Page 17 Regulator Full output current not available at high input-output voltages High Current Adjustable Regulator 17 Power Follower www. Views Read Edit View history.
Accidenti come scotta questo transistor. For large voltage differences, the energy lost as heat can ultimately be greater than that provided to the circuit. Of Pins 3 Output Current 1. Linear integrated circuits Voltage regulation. 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.
The output current is that resulting from dropping the reference voltage across the resistor. If the adjustment pin is connected to ground the output pin delivers a regulated voltage of 1.
The LM is designed to compensate for these fluctuations internally, making such measures unnecessary.
Retrieved 31 March Higher regulated voltages are obtained by connecting the adjustment pin to a resistive voltage divider between the output and ground. REF The reference voltage is impressed across program resistor Datasheft and, since the voltage is constant, a constant current I Further, both line and load regulation are better than.
