78xx – Wikipedia

There are many other ways in which the IC can be used based on your application. The circuit diagram for those can be found at the datasheet given at the end of this page. 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. Some devices provide slightly different voltages than usual, such as the LM78L62 6.

The LM78S40 from Fairchild is not part of the 78xx family and does not use the same design.

For the years, see 8th millennium. In other projects Wikimedia Commons. Encyclopedia of Electronic Components Volume 1: Views Read Edit View history. The Input and output capacitors C1 10uF and C2 1uF are used to filter noise from the input and the output voltage respectively.

LM7912 Datasheet

The 78xx family is commonly used in electronic circuits requiring a regulated power supply due to their ease-of-use and low cost. January Learn how and when to remove this template message.

I have used a Battery xatasheet power the IC, but you can use any power source but notice that the supply voltage should be negative. There is a related line of 79xx devices which are complementary negative voltage regulators. The 78xx line are positive voltage regulators: Complete Technical Details can be found at the datasheet given at the end of this page.

Hence, I have interchanged the polarity of the battery. Available in TO package only.

Please help improve this article by adding citations to reliable sources. Unsourced material may be challenged and removed. In both cases will be an ideal choice when you need a negative 12V.

Articles needing additional references from January All articles needing additional references. The output current of this IC is upto 1A, however with appropriate heat sink the datasheet says that a peak current of 2. These devices support an input voltage anywhere from around 2. TL dztasheet Programmable Reference Voltage. Cool Projects for Open Source Hardware.

The negative output voltage is obtained from the Vo 3rd Pin which is also read using a Multimeter. The is the most common, as its regulated 5-volt supply provides a convenient power source for most TTL components. From Wikipedia, the free datasheet. By using this site, you agree to the Terms of Use and Privacy Policy. Meaning it will provide a constant output voltage of V when the input voltage is between When you are designing an analog circuitthe circuit might need negative voltage either as a power source or as a reference voltage.
