I am driving a PIR sensor for a scopeclock. If a 78xx series regulator’s output happens to be higher than what you want due to factory tolerances you are stuck. Industrial Electronics and Control.

Apr 19, 5. Apr 19, 2.

If you omit these caps, you may have instability problems high frequency oscillations and reduced output voltage. I think you meant ? The LM78S40 from Fairchild is not part of the 78xx family and does not use the same design. When building a 3v power supply, why not use a voltage regulator in place of a LM?

Some devices provide slightly different voltages than usual, such as the LM78L62 6.

LM Datasheet – 1A, V Switching Regulator – Ten Power

You can add more capacitors if you like, but you must have those two present. In other projects Wikimedia Commons.


From Wikipedia, the free encyclopedia. This page was last edited on 5 Decemberat For the years, see 8th millennium. The is a switching regulator – which is an entirely different topology for voltage regulators.

The 78xx family is commonly used in electronic circuits requiring a regulated power supply due to their ease-of-use and low cost. Note that the 78xx series regulators require a 0. This article needs additional citations for verification. With a LM, you can adjust the output right where you want it; anywhere from about 1.

Retrieved from ” https: 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 ICs.
