When you are designing an analog circuitthe circuit might need negative voltage either as a power source or as a reference voltage. The output current of this IC is upto 1A, however with appropriate heat sink the datasheet says that a peak current of 2. 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. Encyclopedia of Electronic Components Volume 1: In other projects Wikimedia Commons.

The 78xx family is commonly used in electronic circuits requiring a regulated power supply due to their ease-of-use and low cost. The circuit diagram for those can be found at the datasheet given at the end of this page. This dataaheet needs additional citations for verification. 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. Articles needing additional references from January All articles needing additional references.


TL — Programmable Reference Voltage. Cool Projects for Open Source Hardware.

It is a component in switching regulator designs and is not a linear regulator like other 78xx devices. 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.

For the years, see 8th millennium. Submitted by webmaster on 23 November These devices support an input voltage anywhere from around 2.

LM from Texas Instruments

There are many other ways in which the IC can be used based on your application. 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. In both cases will be an ideal choice when you need a negative 12V. The Input and output capacitors C1 10uF and C2 1uF are used to filter noise from the input and the output voltage respectively.

Retrieved from ” https: LM belongs to the family of Voltage regulators. The is the most common, as its regulated 5-volt supply provides a convenient power source for most TTL components. Hence, I have interchanged the polarity of the battery. The negative output voltage is obtained from the Vo 3rd Pin which is also read using a Multimeter.


Some devices provide slightly different voltages than usual, such as the LM78L62 6.

January Learn how and when to remove this template message. Please help improve this article by adding citations to reliable sources. Meaning it will provide a constant output voltage of V when the input voltage is between Complete Technical Details can be found at the datasheet given at the end of this page. There is a related line of 79xx devices which are complementary negative voltage regulators.

LM Applications Constant V output regulator to use as power or reference voltage for analog and digital circuits. Views Read Edit View history. The 78xx line are positive voltage regulators: This page was last edited on 5 Decemberat Mastering the Raspberry Pi.
