Because some quiescent current flows from the adjustment pin of the device, dtaasheet error term is added:. It was designed by Robert “Bob” Pease. From Wikipedia, the free encyclopedia.

LM317BT Datasheet

This voltage regulator is exceptionally easy to use and requires only two external resistors to set the output voltage. The output current is that resulting from dropping the reference voltage across the resistor. The LM is an adjustable analogue to the popular 78xx fixed regulators. Linear integrated circuits Voltage regulation. Floating Operation for High Voltage Applications 7.

How the adjustment pin is connected determines the output voltage as follows. Archived from the original PDF on 18 April The alternative is to use a switching voltage regulator which is usually more efficient but has lm317tb larger footprint and requires a larger number of associated components. The LM has three pins: The LM is designed to compensate for these fluctuations internally, making such measures unnecessary.


1.5 A Adjustable Output, Positive Voltage Regulator

Eliminates Stocking many Fixed Voltages. The LM relates in the same way to the fixed 79xx regulators.

In use an LM commonly requires a heat sink to prevent the operating temperature rising too high. Accidenti come scotta questo transistor. Retrieved 31 March Because of this, the error term in the formula cannot be ignored and the value of the low-side resistor becomes more critical.

Further, it employs internal current limiting, thermal shutdown and safe area compensation, making it essentially blow—out proof. 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.

Three-Terminal Positive Voltage Regulator. If the adjustment pin is connected to ground the output pin delivers a regulated voltage of 1. Failure to do this may cause the circuit to short. The device can be configured to regulate the current to a load, rather than the voltage, by replacing the low-side resistor datashet the divider with the load itself.

In other projects Wikimedia Commons. The LM is an adjustable 3—terminal positive voltage regulator capable of supplying in excess 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 voltage for V ref e.


For large voltage datssheet, the energy lost as heat can ultimately be greater than that provided to the circuit. The LM negative complement to the LM regulates voltages below, rather than above, the reference. The LM serves a wide variety of applications including local, on card regulation.

Archived from the original on 17 December 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 “. By using this site, you agree to the Terms of Use and Privacy Policy.

Higher regulated voltages are obtained by connecting the adjustment lm317nt to a resistive voltage divider between the output and ground.
