The is the most common, as its regulated 5-volt supply provides a convenient power source for most TTL components. In both cases will be an ideal choice when you need a negative 12V. Mastering the Raspberry Pi. The Input and output capacitors C1 10uF and C2 1uF are used to filter noise from the input and the output voltage respectively.

78xx – Wikipedia

Hence, I have interchanged the polarity of the battery. Please help improve this article by adding citations to reliable sources. The 78xx line are positive voltage regulators: Km7912 — Programmable 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.

Submitted by webmaster on 23 November Articles needing additional references from January All articles needing additional references. The output current of this IC is upto 1A, however with appropriate heat sink the datasheet says that a peak current of 2. Cool Projects for Open Source Hardware.


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. You dayasheet also check on 78 series for positive voltage regulators.

LM 7912 CT

From Wikipedia, the free encyclopedia. These devices support an input voltage anywhere from around 2. The circuit daatsheet 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. Encyclopedia of Electronic Components Volume 1: Industrial Electronics and Control. LM belongs to the family of Voltage regulators. There are many other ways in which the IC can be used based on your application. The value of the capacitors need not be the exact values, you can use the closest value you have got.

A very basic Voltage regulator circuit is shown below.

There is a related line of 79xx devices which are complementary negative voltage regulators. Unsourced material may be challenged and removed. Views Read Edit View history. 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. Some devices provide slightly different voltages than usual, such datasheft the LM78L62 6.
