lm 3V Positive Voltage Regulator datasheet & applicatoin notes – Datasheet Archive

The LM78S40 from Fairchild is not part of the 78xx family and does not use the same design. Please help improve this article by adding citations to reliable sources. Articles needing additional references from January All articles needing additional references. Improving on the Electret: The is a switching regulator – which is an entirely different topology for voltage regulators.


Datashwet Feedback, Part 6: Apr 19, 4. You can add more capacitors if you like, datasheft you must have those two present.

Am I missing something? Switchers often inject high frequency noise into surrounding circuitry.

Some devices provide slightly different voltages than usual, such as the LM78L62 6. The LM has somewhat better om7803 and eatasheet current rating than the 78xx series. Do you already have an account? Apr 19, 1. I think you meant ? With a LM, you can adjust the output right where you want it; anywhere from about 1.

Cool Projects for Open Source Hardware. Your name or email address: Note that the 78xx series regulators require a 0.

LM7803-1A Datasheet PDF

The LM is a linear regulator – so depending on your input voltage, you could dissipate a lot of heat through it, and waste power. Are you doing this for work?

This article needs additional citations for verification. You May Also Like: These devices support an input voltage anywhere from datahseet 2. The is the most common, as its regulated 5-volt supply provides a convenient power source for most TTL components. January Learn how and when to remove this template message.


LM Datasheet, PDF – Alldatasheet

It is a component in switching regulator designs and is not a linear regulator like other 78xx devices. If a 78xx series regulator’s output happens datahseet be higher than datawheet you want due to factory tolerances you are stuck. Encyclopedia of Electronic Components Volume 1: Apr 19, 3. When building a 3v power supply, why not use a voltage regulator in place of a LM?

I am driving a PIR sensor for a scopeclock. This page was last edited on 5 Decemberat For the years, see 8th millennium.
