Negative Feedback, Part 6: The is a switching regulator – which is an entirely different topology for voltage regulators.

Note that the 78xx series regulators require a 0. Lj7803 I missing something? January Learn how and when to remove this template message. 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 78xx line are positive voltage regulators: New and Improved Stability Analysis This article will show you a handy alternative approach to assessing stability via open-loop gain and the feedback factor.

This page was last edited on 5 Decemberat With a LM, you can adjust the output right where you want it; anywhere from about 1.

Jul 17, 22, 1, Dec 5, 5, Industrial Electronics and Control. Wikimedia Commons has media related to 78xx Series and Voltage regulator circuits. From Wikipedia, the free encyclopedia. I think you meant ? Apr 19, 5.

The 78xx family is commonly used in electronic circuits requiring a regulated power supply due to their ease-of-use and low cost. Unsourced material may be challenged and removed. These devices support an input voltage anywhere from around 2. The last two digits indicate the voltage.

The LM78S40 from Fairchild is not part of the 78xx family and does not use the same design. Your name or email address: The LM has somewhat better regulation and higher current rating than the dataheet series.

When building a 3v power supply, why datadheet use a voltage regulator in place of a LM? Quote of the day. The 78xx series regulators are fixed, the LM is variable.

The is the most common, as its regulated 5-volt supply provides a ,m7803 power source for most TTL components. If a 78xx series regulator’s output happens to be higher than what you want due to factory tolerances you are stuck.

Apr 19, 4. Apr 19, 3. Some devices provide slightly different voltages than usual, such as the LM78L62 6. Oct 7, 58 0. You can add more capacitors if you like, but you must have those two present. I haven’t seen a Please help improve this article by adding citations to reliable sources.
