These devices support an input voltage anywhere from around 2. The Input and output capacitors C1 10uF l,7912 C2 1uF are used to filter noise from the input and the output voltage respectively. Views Read Edit View history.

Articles needing additional references from January All articles needing additional references. Submitted by webmaster on 23 November TL — Programmable Datawheet Voltage. Encyclopedia of Electronic Components Volume 1: Cool Projects for Open Source Hardware.

In both cases will be an ideal choice when you need a negative 12V. This page was last edited on 5 Decemberat Some devices provide slightly different voltages than usual, such as the LM78L62 6. A very basic Voltage regulator circuit is shown below. There are many other ways in datashheet the IC can be used based on your application.

The LM78S40 from Fairchild is not part of the 78xx family and does not use the same design. Datazheet value of the capacitors need not be dstasheet exact values, you can use the closest value you have got. 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.

There is a related line of 79xx devices which are complementary negative voltage regulators. By using this site, you agree to the Terms of Use and Privacy Policy. The is the most common, as its regulated 5-volt supply provides a convenient power source for most TTL components.

Available in TO package only. Datasueet Applications Constant V output regulator to use as power or reference voltage for analog and digital circuits.

Please help improve this article by adding citations to reliable sources. In other projects Wikimedia Commons. This article needs additional citations for verification. Mastering the Raspberry Pi. I have used a Battery to power the IC, but you can use any power source but notice that the supply voltage should be negative. The output current of this IC is upto 1A, however with appropriate heat sink the datasheet says that a peak current of 2.


Wikimedia Commons has media related to 78xx Series and Voltage regulator circuits. Hence, I have interchanged the polarity of the battery.

You can also check on 78 series for positive voltage regulators. The 78xx line are positive voltage regulators: Unsourced material may be challenged and removed.

January Learn how and when to remove this template message. 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.

It is a component in switching regulator designs and is not a linear regulator like other 78xx devices. Complete Technical Details can be found dahasheet the datasheet given at the end of this page. The 78xx family is commonly used in electronic circuits requiring a regulated power supply due to their ease-of-use and low cost. LM belongs to the family of Voltage regulators. Retrieved from ” https: The negative output voltage is obtained from the Vo 3rd Pin which is also read using a Multimeter.
