Three-Terminal Positive Voltage Regulator. 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 lm17bt heat sink from other parts of the application circuit.

Because some quiescent current flows from the adjustment pin of the device, an error term is added:. It was designed by Robert “Bob” Pease. The LM is an adjustable analogue to the popular 78xx fixed regulators.

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. Output Current in Excess of 1. Three-terminal adjustible output positive voltage regulator.

This page was last edited on 6 Julyat Datashet other projects Wikimedia Commons. The output current is that resulting from dropping the reference voltage across the resistor. Output Adjustable between 1. Archived from the original PDF on 31 March In use an LM commonly requires a heat sink to prevent the operating temperature rising too high.

Higher regulated voltages are obtained by connecting the adjustment pin to a resistive voltage divider between the output and ground. Linear integrated circuits Voltage regulation. Linear regulators inherently waste power, the power dissipated is the current passed multiplied by the voltage difference between input and output. Internal Thermal Overload Protection 4. The LM is designed to compensate for these fluctuations internally, making such measures unnecessary.

Three-terminal positive voltage regulator. The LM serves a wide variety of applications including local, on card regulation. This device can also be used to make a programmable output regulator, or by connecting a fixed resistor between the adjustment and output, the LM can be used as a precision current regulator.

Retrieved from ” https: This is the trade-off for using linear regulators which are lm37bt simple way to provide a stable voltage with few additional components. From Wikipedia, the free encyclopedia.

Views Read Edit View history. Failure to do this may cause the circuit to short. Because of this, the error term in the formula cannot be ignored and the value of the low-side resistor becomes more critical.

Three Terminal Positive Voltage Regulator. The LM is an adjustable 3—terminal positive voltage regulator capable of supplying in excess of 1.

Output Transistor Safe—Area Compensation 6. 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.
