By using this site, you agree to the Terms of Use and Privacy Policy. The output current of this IC is upto 1A, however with appropriate heat sink the datasheet says that a peak current of 2. You can also check on 78 series for positive voltage regulators. There is a related dattasheet of 79xx devices which are complementary negative voltage regulators.

Retrieved from ” https: The LM78S40 from Ln7912 is not part of the 78xx family and does not use the same design. Mastering the Raspberry Pi.

LM Pinout, Features, Equivalents & Datasheet

For the years, see 8th millennium. Articles needing additional references from January All articles needing additional references. LM belongs to the family of Voltage regulators.


The negative output voltage is obtained from the Vo 3rd Pin which is also read using a Multimeter. It is a component in switching regulator designs and is not a datasheft regulator like other 78xx devices. Complete Technical Details can be found at the datasheet given at the end of this page. I have used a Battery datashet power the IC, but you can use any power source but notice that the supply voltage should be negative.

Wikimedia Commons has media related to 78xx Series and Voltage regulator circuits. From Wikipedia, the free encyclopedia.

LM7912 Datasheet

The is the most common, as its regulated 5-volt supply provides a convenient power source for most TTL components. In other projects Wikimedia Commons.

Available in TO package only. Meaning it will provide a constant output voltage of V when the input voltage is between Industrial Electronics and Control.

Hence, I have interchanged the polarity of the battery. Submitted by webmaster on 23 November Encyclopedia of Electronic Components Volume 1: Views Read Edit View history.

This page was last edited on 5 Decemberat These devices support an input voltage anywhere from around 2. The 78xx line ratasheet positive voltage regulators: 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. Some devices provide slightly different voltages than usual, such as the LM78L62 6. In both cases will be an ideal choice when you need a negative 12V.

Cool Projects for Open Source Hardware. There are many other ways in which the IC can be used based on your application. 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. The Input and output capacitors C1 10uF and C2 1uF are used to filter noise from the input and the output voltage respectively.

LM Applications Constant V output regulator to use datasneet power or reference voltage for analog and digital circuits. TL — Programmable Reference Voltage. Unsourced material may be challenged and removed.
