Please help improve this article by adding citations to reliable sources. The SR from Datel is a full switching power supply module designed as a drop-in replacement for 78xx chipsand not a linear regulator like the 78xx Dtaasheet.

With a LM, you can adjust the output right where you want it; anywhere from about 1. If a 78xx series regulator’s output happens to be higher than what you want due to factory tolerances you are stuck.


The LM78S40 from Fairchild is not part of the 78xx family and does not use the same design. Oct 7, 58 0. Are you doing this for work? If you omit these caps, you may have instability problems high frequency oscillations and reduced output voltage. The is the most common, as its regulated 5-volt supply provides a convenient power source for l7m803 TTL components. 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.

Apr 19, 1. The 78xx series regulators are fixed, the LM is variable. Jul 17, 22, 1, The is a switching regulator – which is an entirely different topology for voltage regulators. There is a related line of 79xx devices which are complementary negative voltage regulators.

78xx – Wikipedia

Switchers often inject high frequency noise into surrounding circuitry. The LM is a linear regulator – so depending on your input voltage, you could dissipate a lot of heat through it, and waste power. Yes, my password is: Note that the 78xx series regulators require a 0. The 78xx line are positive voltage regulators: The last two digits indicate the voltage.

Negative Feedback, Part 6: Apr 19, 5. Articles needing additional references from January All articles needing additional references. Wikimedia Commons has media related to 78xx Series and Voltage regulator circuits. You can add more capacitors if you datasheef, but you must have those two present. Unsourced material may be challenged and removed.


When building a 3v power supply, why not use a voltage regulator in place of a LM? You May Also Like: I think you meant ? It is a component in switching regulator designs and is not a eatasheet regulator like other 78xx devices. Your name or email address: Improving on the Electret: Apr 19, 4.

LM317 vs. 7803

Apr 14, Encyclopedia of Electronic Components Volume 1: January Learn how and when to remove this template message. Retrieved from ” https: The LM has somewhat better regulation and higher current datashret than the 78xx series. Quote of the day.

This page was last edited on 5 Decemberat Some devices provide slightly different voltages than usual, such as the LM78L62 6. Using a LM requires 2 to 3 resistors, does not. Cool Projects for Open Source Hardware.
