What are the lm217 and LM317 circuits?

What are the lm217 and LM317 circuits?

The LM217, LM317 are monolithic integrated circuits in TO-220, TO-220FP and D²PAK packages intended for use as positive adjustable voltage regulators. They are designed to supply more than 1.5 A of load current with an output voltage adjustable over a 1.2 to 37 V range.

What is an LM317 regulator?

The LM317 is an adjustable three-terminal positive-voltage regulator capable of supplying more than 1.5 A overan output-voltage range of 1.25 V to 37 V. It is exceptionally easy to use and requires only two external resistorsto set the output voltage. Furthermore, both line and load regulation are better than standard fixed regulators.

How to adjust the output of LM317 IC?

The LM317 IC develops and maintains 1.25V between its output and adjustment pin. Its output can be adjusted by connecting a network of two resistors externally between the output pin and adjust the input pin. The two decoupling capacitors are connected in a circuit. They are used to remove the undesired coupling and avoid the effect of noise.

What are the LM317 current boosting secrets?

LM317 Current Boosting Secrets! Introduction: LM317 Current Boosting Secrets! LM317 is one of the most popular adjustable regulator chips. The output voltage of the regulator can be adjusted from 1.25V to 35V. However, the chip can deliver currents up to 1.5A which is not enough for some power applications.

Why do we use voltage regulators in LM317 ICS?

It can supply greater than 1.5 A at the output. In most of the applications, due to irregular loads, the output voltage produced has fluctuations in it which can lead to damaging loads. Therefore, voltage regulators are used. The main function of the LM317 IC is to maintain the constant and stable voltage at the output.

What are the applications of LM317?

The applications of LM317 includes: 1 It is a positive voltage regulator and hence used in the regulation of positive voltages. 2 It is used in designing current-limiter circuits which keeps the output current in limits. More

Which device is used for linear regulation of the output?

It is 3 terminal device used for linear regulation of the output. The details of pins are as under: Pin1 is an adjustable pin which is used to adjust the output voltage. Pin2 is an output pin and gives a regulated voltage.
