![]() It was designed by Bob Dobkin in 1976 while he worked at National Semiconductor.IC regulator tegangan variabel LM317 memiliki kemampuan mengalirkan arus maksimum sebesar 1,5 Ampere dan mampu memberikan tegangan output variabel dari 1,2 volt DC sampai dengan 37 volt DC. ![]() Operating Condition of LM317 IC from the Datasheet voltage, current, temperature rating, etc.LM317 with heat sinkThe LM317 is a popular adjustable positive linear voltage regulator. ![]() So in this video, I have explained the following topic of LM317 IC which gives you a clear idea about the LM317 regulator. *Persamaan Ic Lm317t*Persamaan Ic Regulator Lm317Now, before working with the LM317 voltage regulator, we should know the pros corns of the LM317.

You can also verify the results by putting resistors values in the formula given above. To achieve high ripple rejection ratios, bypass the ADJUST terminal. Therefore, in some applications, protection diodes are added which prevent the capacitors from discharging. The external capacitors can discharge due to the low current of the regulator. These capacitors help to remove ripples from output voltage.įor this reason, a heat sink is used to protect the IC from overheating. Download software east west quantum leap stormdrum kompakt edition ![]() However, we can also use capacitors to avoid voltage variations at the input and output terminals. To use it is a variable regulator, we have connected a potentiometer at the adjustable pin.īy changing the value of a potentiometer, you can obtain the desired voltage at the output. They are used to remove the undesired coupling and avoid the effect of noise.Ī capacitor of 1F is connected at the output to improve transient response. Its output can be adjusted by connecting a network of two resistors externally between the output pin and adjust the input pin. It has one drawback that during regulation its voltage drop to about 2.5V. ![]() It can be used as a fixed voltage regulator, AC voltage regulator, current limiter, Battery charger, local and on-card regulation.įurthermore, it can be used as a current regulator by connecting a resistor between the output and adjustment pin. ![]()
