Further, both line and load regulation are better than. The LM series of adjustable 3-terminal positive voltage.

Of Pins 3 Output Current 1. In use an LM commonly requires a heat sink to prevent the operating temperature rising too high. The LM has three pins: However, the 78xx device’s quiescent current is substantially higher and less stable. Higher regulated voltages are obtained by connecting the adjustment pin to a resistive voltage divider between the output and ground.

It was designed by Robert “Bob” Pease. For large voltage differences, the energy lost as heat can ultimately be greater than that provided to the circuit. In addition to higher performance than fixed regulators, the.

Also, the LM is packaged in. Page 27 Notes 27 www. Retrieved from ” https: Prev Next 3-Terminal Adjustable Regulator.

Regulator Full output current not available at high input-output voltages High Current Adjustable Regulator 17 Power Follower www. LM can be used as a precision current regulator. REF The reference voltage is impressed across program resistor R1 and, since the voltage is constant, a constant current I Copy your embed code and put on your site: 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. 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 voltage for V ref e.

This is the trade-off for using linear regulators which are a simple way to provide a stable voltage with few additional components. The LM relates in the same way to the fixed 79xx regulators.

LM series offers full overload protection available only in. Page 18 Current Regulator 1.

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. Linear regulators inherently waste power, the power dissipated is the current passed multiplied by the voltage difference between input and output.

Dataxheet the adjustment pin is connected determines the output voltage as follows. The output current is that resulting from dropping the reference voltage across the resistor. Retrieved 31 March The LM negative complement to the LM regulates voltages below, rather than above, the reference. Of Outputs 1 No.
