The LM78S40 from Fairchild is not part of the 78xx family and does not use the same design.
Retrieved from ” https: The negative output voltage is obtained from the Vo 3rd Pin which is also read using a Multimeter. This article needs additional citations for verification.
LM7912 Datasheet PDF
Available in TO package only. These devices support an input voltage anywhere from around 2.
There is a related line of 79xx devices which are complementary negative voltage regulators. You can also check on 78 series for positive voltage regulators. LM Applications Om7912 V output regulator to use as power or reference voltage for analog and digital circuits.
LM Pinout, Features, Equivalents & Datasheet
In both cases will be an ideal choice when you need a negative 12V. Mastering the Raspberry Pi. January Learn how and when to remove this template message. There are many other ways in which the IC can be used based on your application.
The 78xx line are positive voltage regulators: 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 circuit diagram for those can be found at the datasheet given at the end of this page. Wikimedia Commons has media related to 78xx Series and Voltage regulator circuits. The 78xx family is commonly used in electronic circuits requiring a regulated power supply due to their ease-of-use dataaheet low cost.
Meaning it will provide a constant output voltage of V when the input voltage is between Datashert is the most common, as its regulated 5-volt supply provides a convenient power source for most TTL components.
Hence, I have interchanged the polarity of the battery. Articles needing additional references from January All articles needing additional references.

Some devices provide slightly different voltages than usual, such as the LM78L62 6. It is a component in switching regulator designs and is not a linear regulator like other 78xx devices. Complete Technical Details can be found at the datasheet given at the end of this pm7912. A very basic Voltage regulator circuit is shown below. Industrial Electronics and Control. This page was last edited on 5 Decemberat The Input dztasheet output capacitors C1 10uF and C2 1uF are used to filter noise from the input and the output voltage respectively.
When you are designing an analog circuitthe circuit might need negative voltage either as a power source or as a reference voltage.
