Encyclopedia of Electronic Components Volume 1: Industrial Electronics and Control. 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. For the years, see 8th millennium.

LM Pinout, Features, Equivalents & Datasheet

The LM78S40 from Fairchild is not part of the 78xx family and does not use the same design. Hence, I have interchanged the polarity of the battery. The is datashedt most common, as its regulated 5-volt supply provides a convenient power source for most TTL components.

From Wikipedia, the lm712 encyclopedia. Some devices provide slightly different voltages than usual, such as the LM78L62 6. By using this site, you agree to the Terms of Use and Privacy Policy. Unsourced material may be challenged and removed. There are many other ways in which the IC datashee be used based on your application. The Input and output capacitors C1 10uF and C2 1uF are used to filter noise from the input and the output voltage respectively.


Please help improve this article by adding citations to reliable sources. Retrieved from ” https: These devices support an input voltage anywhere from around 2. The value of the capacitors need not be the exact values, you can use the closest value vatasheet have got.

You can also check on 78 series for positive voltage regulators. 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. I have used a Battery to power the IC, but you datasheer use any power source but notice that the supply voltage should be negative.

LM7912 Datasheet PDF

Available in TO package only. This article needs additional dstasheet for verification. The negative output voltage is obtained from the Vo 3rd Pin which is also read using a Multimeter. The 78xx line are positive voltage regulators: In other projects Wikimedia Commons. In both cases will be an ideal choice when you need a negative 12V. Submitted by webmaster on 23 November Cool Projects for Open Source Hardware.


Complete Technical Details can be found at the datasheet given at the end of this page. TL — Programmable Reference Voltage. Articles needing additional references from January All articles needing additional references. Meaning it will provide a constant output voltage of V when the input voltage is between Mastering the Raspberry Pi.

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. The 78xx family is commonly used in electronic circuits requiring a regulated power supply due to their ease-of-use and low cost.

A very basic Voltage regulator circuit is shown below.


LM belongs to the family of Voltage regulators. Views Read Edit View history. This page was last edited on 5 Decemberat
