PDF LM338K Datasheet ( Hoja de datos )
Although the LM is stable with no output capacitors, like any feedback circuit, certain values of external capacitance can cause excessive ringing. Regulator with Line Resistance in Output Lead.
Integrating ADC wikipedialookup. Two-port network wikipedialookup.
Solar micro-inverter wikipedialookup. When an output capacitor is connected to a regulator and the input is shorted, the output capacitor will discharge into the output of the regulator.
Under sustained loading conditions, the lm3338k limit decreases to a safe value protecting the regulator. This eliminates line drops from appearing effectively in series with the reference and degrading regulation.
Changes in output voltage due to heating effects are taken into account separately by datashet rejection. Besides replacing fixed regulators or discrete designs, the LM is useful in a wide variety of other applications.
Opto-isolator wikipedialookup. Current mirror wikipedialookup. An optional output capacitor can be added to improve transient response.
Datasheer, other values such as or ohms can ratasheet be used for R 1. The dropout voltage of the IC regulator is about 1. This bypass capacitor prevents ripple form being amplified as the output voltage is increased. Ohm’s law wikipedialookup. 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 lm338.
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. To determine the output voltage, enter values for the program R 1 and set R 2 resistors and hit the “Calculate” button.
Created 28 July An input bypass capacitor is recommended. Power inverter wikipedialookup.
Ceramic capacitors are also good at high frequencies, but some types have a large decrease in capacitance at frequencies around 0. Lm3388k ground of R2 can be returned near the ground of the load to provide remote ground sensing and improve load regulation.
The bypass capacitor on the adjustment terminal can datasheet through a low current junction. In the LM this discharge path is through a large junction that is able to sustain 25A surge with no problem. In general, the best type of capacitors to use are solid tantalum.
National Semiconductor – datasheet pdf
Voltage optimisation wikipedialookup. Even small capacitors can have a low enough internal series resistance to be able to deliver 20A spikes when shorted. Regulation is measured at constant junction temperature. Solid tantalum capacitors have low impedance even at high frequencies. Distribution management system wikipedialookup. Normally, no capacitors are needed unless the device is situated far from the input filter capacitors in which case an input bypass is needed.
Switched-mode power supply wikipedialookup. Last update 6 January Tube sound wikipedialookup. Where greater output current is required, the LM series regulators are suitable up to datadheet and the LM series voltage regulators for up dataxheet 5A of output.
The LM voltage regulators can provide up to 1. Transistor wikipedialookup. Islanding wikipedialookup. Pulse-width modulation wikipedialookup. Mains electricity wikipedialookup. Rectifier wikipedialookup. Capacitor wikipedialookup.
