Dec 5, 5, Using a LM requires 2 to 3 resistors, does not. The is the most common, as its regulated 5-volt supply provides a convenient power source for most TTL components.

Apr 19, 3. Industrial Electronics and Control. The LM78S40 from Fairchild is not part of the 78xx family and does not use the same design. No, create an account now. Some devices provide slightly different voltages than usual, such as the LM78L62 6. Mastering the Raspberry Pi.

Please help improve this article by adding citations to reliable sources. You May Also Like: In other projects Wikimedia Commons. With a LM, you can adjust the output right where you want it; anywhere from about 1. When building a 3v power supply, why not use a voltage regulator in place of a LM?

Encyclopedia of Electronic Components Volume 1: Retrieved from ” https: The last two digits indicate the voltage. You CAN increase the output voltage of the 78xx series by adding resistors. Apr 14, The LM is a linear regulator – so depending on your input voltage, you could dissipate a lot of heat through it, and waste power. The is a switching regulator – which is an entirely different topology for voltage regulators.

I think you meant ? Articles needing additional references from January All articles needing additional references. Negative Feedback, Part 6: There is a related line of 79xx devices which are complementary negative voltage regulators. January Learn how and when to remove this template message.

Am I missing something? The 78xx family is commonly used in electronic circuits requiring datasgeet regulated power supply due to their ease-of-use and low cost. Quote of the day.
