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 “.

In addition to higher performance than fixed regulators, the.

lm117b If the adjustment pin is connected to ground the output pin delivers a regulated voltage of 1. REF The reference voltage is impressed across program resistor R1 and, since the voltage is constant, a constant current I Output capacitors in the range.

The output current is that resulting from dropping the reference voltage across the resistor. The LM relates in the same way to the fixed 79xx regulators.

Failure to do this may cause the circuit to short. Retrieved 31 March Regulator Full output current not available at high input-output voltages High Current Adjustable Regulator 17 Power Follower www.

Linear integrated circuits Voltage regulation. The LM negative complement to the LM regulates voltages below, rather than above, the reference. Normally, no capacitors are needed unless the device is sit.

In use an LM commonly requires a heat sink to prevent the operating temperature rising too high. For applications requiring greater output current, see LM All other trademarks are the property of their respective owners.

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.

Application Hints In operation, the LM develops a nominal 1. Lm1117h, the LM is packaged in. The guaranteed specifications apply only for the test conditions listed. An optional output ca.

Included on the chip are current limit, thermal overload. Also, it makes an especially simple adjustable switching reg.


Higher regulated voltages are obtained by connecting the adjustment pin to a resistive voltage divider between the output and ground. This page was last edited on 6 Julyat In other projects Wikimedia Commons. Full output current not available at high input-output voltages.
