You can also check on 78 series for 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. From Wikipedia, the free encyclopedia. January Learn how and when to remove this template message. For the years, see 8th millennium. It is a component in switching regulator designs and is not a linear regulator like other 78xx devices.
LM belongs to the family of Voltage regulators. The 78xx family is ln7912 used in electronic circuits requiring a regulated power supply due to their ease-of-use and low cost. The value of the capacitors need not be the exact values, you can use the closest value you have got.

PDF LM7912 Datasheet ( Hoja de datos )
Lm79122 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. Available in TO package only. The circuit diagram for those can be found at the datasheet given at the end of this page. LM Applications Constant V output regulator to use as power or reference voltage for analog and digital circuits.
Dataheet needing additional references from January All articles needing additional references. Please help improve this article by adding citations to reliable sources. Some devices provide slightly different voltages than usual, such as the LM78L62 6.
I have used a Battery to power the IC, but you can use any power source but notice that the supply voltage should datashset negative.
LM Hoja de datos ( Datasheet PDF ) – 3 TERMINAL 1A NEGATIVE VOLTAGE REGULATOR
TL — Programmable Reference Voltage. Retrieved from ” https: These devices support an input voltage anywhere from around 2.
In both cases will be an ideal choice when you need a negative 12V. Submitted by webmaster on 23 November Encyclopedia of Electronic Components Volume 1: The is the most common, as its regulated 5-volt supply provides a convenient power source for most TTL components. Meaning it will provide a constant output voltage of V when the input voltage is between Industrial Electronics and Control. There is a related line of 79xx devices which are complementary negative voltage regulators.
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.
This page was last edited on 5 Decemberat The LM78S40 from Fairchild is not part of the 78xx family and does not use the same design. A very basic Voltage regulator circuit is shown below. This article datqsheet additional citations for verification. Cool Projects for Open Source Hardware. Mastering the Raspberry Pi.
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: There are many other ways in which the IC can be used based on your application. In other projects Datsaheet Commons. Complete Technical Details can be found at the datasheet given at the end of this page.
