Some devices datasheeet slightly different voltages than usual, such as the LM78L62 6. I haven’t seen a These devices support an input voltage anywhere from around 2. It is a component in switching regulator datxsheet and is not a linear regulator like other 78xx devices. Encyclopedia of Electronic Components Volume 1: For the years, see 8th millennium.

The is the most common, as its regulated 5-volt supply provides a convenient power source for most TTL components. Apr 19, 4.

You can add more capacitors dztasheet you like, but you must have those two present. No, create an account now. By using this site, you agree to the Terms of Use and Privacy Policy.


Cool Projects for Open Source Hardware. Apr 19, 1. There is a related line of 79xx devices which are complementary negative voltage regulators. The 78xx series regulators are fixed, the LM is variable. New and Improved Stability Analysis This article will llm7803 you a handy alternative approach to assessing stability via open-loop gain and the feedback factor.

With a LM, you can adjust the output right where you want it; anywhere from about 1. Retrieved from ” https: Please help improve this article by adding citations to reliable sources.

Am I missing something? Unsourced material may be challenged and removed. Views Read Edit View history. If a 78xx series regulator’s output happens to be dataheet than what you want due to factory tolerances you are stuck. This article needs additional citations for verification. The 78xx family is commonly used in electronic circuits requiring a regulated power supply due to their ease-of-use and low cost.


Wikimedia Commons has media related to 78xx Series and Voltage regulator circuits. The SR from Datel is a full switching power supply module datasheet as a drop-in replacement for datashee chipsand not a linear regulator like the 78xx ICs.

If you omit these caps, you may have instability problems high frequency oscillations and reduced output voltage. Mastering the Raspberry Pi. This page was last edited on 5 Decemberat Are you doing this for work?
