Elcodis is a trademark of Elcodis Company Ltd. This is the trade-off for using linear regulators which are a simple way to provide a stable voltage with few additional components. Also, the Ddatasheet is packaged in. The guaranteed specifications apply only for the test conditions listed. LMH datasheet and specification datasheet. Application Hints In operation, the LM develops a nominal 1.
Failure to do this may cause the circuit to short. Accidenti come scotta questo transistor. Archived from the original PDF on 31 March Output capacitors in the range.

Linear integrated circuits Voltage regulation. The output current is that resulting from dropping the reference voltage across the resistor. Because some quiescent current flows from the adjustment pin of the device, an error term is added:. Included on the chip are current limit, thermal overload. The LM series of adjustable 3-terminal positive voltage.
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. In addition to datqsheet performance than fixed regulators, the. REF The reference voltage is impressed across program resistor R1 and, since the voltage is constant, a constant current I Page 8 Line Transient Response www.

They are exceptionally easy to use. The LM is designed to compensate for these fluctuations internally, making such measures unnecessary.
The LM is an adjustable analogue to the popular 78xx fixed regulators. Layout Top Side Note: Wikimedia Commons has media related to LM and Voltage regulator circuits.
LM117H – LM117 3-Terminal Adjustable Voltage Regulator Datasheet
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.
Of Outputs 1 No. Normally, no capacitors are needed unless the device is sit. Also, it makes an especially simple adjustable switching reg.
This page was last edited on 6 Julyat In use an LM commonly requires a heat sink to prevent the operating temperature rising too high. Higher regulated voltages daatasheet obtained by connecting the adjustment pin to a resistive voltage divider between the output and ground.
All other trademarks are the property of their respective owners. However, the 78xx device’s quiescent current is substantially higher and less lm117u. Page 27 Notes 27 www. Lj117h mechanism used is similar enough that a dagasheet 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.
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 “. Views Read Edit View history. An optional output ca.
