78xx – Wikipedia
It is a component in switching regulator designs and is not a linear regulator like other 78xx devices. Cool Projects for Open Source Hardware.
Hence, I have interchanged the polarity of the battery. There are many other ways in which the IC can be used based on your application. You can also check on 78 series for positive voltage regulators. Unsourced material may be challenged and removed. The LM78S40 from Fairchild is not part of the 78xx family and does not use the same design.
Available in TO package only. There is a related line of 79xx devices which are complementary negative voltage regulators. Submitted by webmaster on 23 November The value of the datashset need not be the exact values, you can datasheey the closest value you have got. This article needs additional citations for verification.
The SR from Datel is a full switching power supply module designed as a drop-in replacement for 78xx lm79112and not a linear regulator like the 78xx ICs.
The Input om7912 output capacitors C1 10uF and C2 1uF are used to filter noise from the input and the output voltage respectively.

January Learn how and when to remove this template message. 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.
A datasheft basic Voltage regulator circuit is shown below.
From Wikipedia, the free encyclopedia. In both cases will be an ideal choice when you need a negative 12V. Please help improve this article by adding citations to reliable sources.
The negative adtasheet voltage is obtained from the Vo 3rd Pin which is also read using a Multimeter.
Articles needing additional references from January All articles needing additional references. These devices support an input voltage anywhere from around 2.
Encyclopedia of Electronic Components Volume 1: The 78xx line are positive voltage regulators: The is the most common, as its regulated 5-volt supply provides a convenient power source for most TTL components.
Complete Technical Details can be found at the datasheet given at the end of this page. Retrieved from ” https: This page was last edited on 5 Decemberat Mastering the Raspberry Pi. When you are designing an analog circuitthe circuit might need negative voltage either as a power source or as a reference voltage.

The 78xx family is commonly used in electronic circuits requiring a regulated power supply due to their ease-of-use and low cost. Some devices provide slightly different voltages than usual, such as the LM78L62 datashret.
