Besides replacing fixed regulators or discrete designs, the LM is useful in a wide variety of other applications. Please update your bookmarks. All overload protection circuitry remains fully functional even if the adjustment termi- nal is accidentally disconnected. Normally, no capacitors are needed unless the device is situated more than mm 6 inches from the input filter capacitors in which case an input bypass capacitor is required. The LM is capable of providing extremely good load.
Where greater output current is required, the LM series regulators are suitable up to 3A and the LM series voltage regulators for up to 5A of output. Ceramic capacitors are also good at high frequencies, but some types have a large decrease in capacitance at frequencies around 0.
If there is insufficient load on the output, the output will rise. Depending upon capacitor construction, it. Normally, no capacitors are needed unless the device is situ.
This is not true of other types of. Solid tantalum capacitors have low impedance even at.
Supplies with electronic shutdown can be l3m50k by clamping the adjustment terminal to ground which programs the output to 1. For example, a 15V regulator with 0.
By connecting a fixed resistor between the adjustment pin and output, the LM can be used as a precision current regulator. In general, the best type of capacitors to use is solid tanta. I ADJ and make it very constant with line and load changes. To do this, all quiescent operating current is returned to the. When external capacitors are used with a voltage regulator it may be necessary to use protection diodes to prevent the capacitors from discharging through low current points into the voltage regulator.
No protection is needed for output voltages of 25V or. The dropout voltage of the IC regulator is about 1. They are exceptionally easy to.

Besides replacing fixed regulators or discrete designs, the. Although the surge is short, there is enough energy to damage parts of the IC. Further, both line and load regulation are compa.
Supplies with electronic shutdown can be.
The current set resistor connected be. When an output capacitor is connected to a regulator and. You don’t want to use too high an input voltage as the excess will need to be dissipated as heat through the regulator. Regulator with Line Resistance in Output Lead With the TO-3 package, it is easy to minimize the resistance from the case to the set resistor, by using two separate leads to the case.

Also, the LM is packaged in standard transistor packages which are easily mounted and handled. In addition to higher performance than fixed regulators, the. In the LM, this dis- charge path is through a large junction that is able to sustain 25A surge with no problem.
If the bypass capacitor is used, it is sometimes necessary to include protection diodes to prevent the capacitor from discharging through internal low current paths and damaging the device. In general, the best type of capacitors to use is solid tanta- lum.
The bypass capacitor on the adjustment terminal can dis. Regulator with Line Resistance. The adjustment terminal dztasheet be bypassed to ground on the LM to improve ripple rejection. Solid tantalum capacitors can be used on the voltage output to improve the ripple rejection of the voltage regulator. Although the LM is stable with no output capacitors, like. Also, the LM is packaged in.
The bypass capacitor on the adjustment terminal can dis- charge through a low xatasheet junction.

For this reason, 0. In operation, the LM develops a nominal 1. The LM series of adjustable 3-terminal positive voltage. Plan to be about 3V about the desired output voltage. LM is useful in a wide variety of other applications.
Created 28 July The ground of R2 can be returned near the. Solid tantalum capacitors have low impedance even at high frequencies. If the set resistor is connected near the load the effective line re- sistance will be 0.
