Some devices provide slightly different voltages than usual, such as the LM78L62 6. The output current of this IC is upto 1A, however with appropriate heat sink the datasheet says lm79122 a peak current of 2.

For the years, see 8th millennium. 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. By using this site, you agree to the Terms of Use and Privacy Policy. Encyclopedia of Electronic Components Volume 1: Please help improve this article by adding citations to reliable sources. There is a related line of 79xx devices which are complementary negative voltage regulators.

This page was last edited on 5 Decemberat The 78xx line are positive voltage regulators: 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 as power or reference voltage for analog and digital circuits.

Views Read Edit View history. Retrieved from ” https: In other projects Wikimedia Commons. LM belongs to the family of Voltage regulators.

January Learn how and when to remove this template message.

LM7912 Datasheet

You can also check on 78 series for positive voltage regulators. There are many other ways in which datahseet IC can be used based on your application. A very basic Voltage regulator circuit is shown below. The value of the capacitors need not be the exact values, you can use the closest value you have got.

The circuit diagram for those can be found at the datasheet given at the end of this page. These devices support an input voltage anywhere from around 2.

lm datasheet & applicatoin notes – Datasheet Archive

Complete Technical Details 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. Submitted by webmaster on 23 November The LM78S40 from Fairchild is not part of the 78xx family and does not use the datashert design.

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. Meaning it will provide a constant output voltage of V when dwtasheet input voltage is between Articles needing additional references from January All articles needing additional references.


Available in TO package only. When you are designing an analog circuitthe circuit might need negative voltage either as a power source or as a 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.

78xx – Wikipedia

From Wikipedia, the free encyclopedia. Hence, I have interchanged the polarity of the battery. This article needs additional citations for verification.

Datxsheet material may be challenged and removed.

TL — Programmable Reference Voltage. Mastering the Raspberry Pi. In both cases will be an ideal choice when you need a negative 12V.

The 78xx family is commonly used in electronic circuits requiring a regulated power supply due to their ease-of-use and low cost. Industrial Electronics and Control. It is a component in switching regulator designs and is not a linear regulator like other 78xx devices.
