Faet Do you already have an account? Dahasheet 78xx series regulators are fixed, the LM is variable. Dec 5, 5, If you omit these caps, you may have instability problems high frequency oscillations and reduced output voltage.
The is a switching regulator — which is an ln different topology for 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. Wikimedia Commons has media related to 78xx Series and Voltage regulator circuits. Am I missing something? Apr 19, 2.
No, create an account now. Apr 14, You CAN increase the output voltage of dataeheet 78xx series by adding resistors. The LM78S40 from Fairchild is not ln of the 78xx family and does not use the same design. The LM has somewhat better regulation and higher current rating than the 78xx series. For the years, see 8th millennium. Jul 17, 22, 1, Apr 19, 5.
Switchers often inject high frequency noise into surrounding circuitry. LM Datasheet catalog Apr 19, 4. In other projects Wikimedia Commons. Cool Projects for Open Source Hardware. You can add more capacitors if you like, but you must have datasheer two present. When building a 3v power supply, why not use a voltage regulator in place of a LM?
The last two digits indicate the voltage. Articles needing additional references from January All articles needing additional references.

Kekus Please help improve this article by adding citations to reliable sources. There is a related line of 79xx llm which are complementary negative voltage regulators. Switchers often inject high frequency noise into surrounding circuitry. Am I missing something? The LM78S40 from Fairchild is not part of the 78xx family and does not use the same design. The LM has somewhat better regulation and higher current rating than the 78xx series.
