Hence, I have interchanged the polarity of the battery. Cool Projects for Open Source Hardware. The 78xx family is commonly used in electronic circuits requiring a regulated power supply due to their catasheet and low cost. It is a component in switching regulator designs and is not a linear regulator like other 78xx devices.

Available in TO package only. This page was last edited on 5 Decemberat For the years, see 8th millennium. Some devices provide slightly different voltages than usual, such as the LM78L62 6. Complete Technical Details can be found at the datasheet given at the end of this page. This article needs additional citations for verification. The value of the capacitors need not be the exact values, you can use the closest value you have got.

Retrieved from ” https: LM belongs to the family of Voltage regulators.

These devices support an input voltage anywhere from around 2. Please help improve this article by adding citations to reliable sources. LM Applications Constant V output regulator to use as power or reference voltage for analog and digital circuits.

Encyclopedia lm77912 Electronic Components Volume 1: You can also check on 78 series for positive voltage regulators.

Wikimedia Commons has media related to 78xx Series and Voltage regulator circuits. The is the most common, as its regulated 5-volt supply provides a convenient power source for most TTL components. 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.

The circuit diagram for those can be found at the datasheet given at the end of this page. I have dataseet a Battery to power the IC, but you can use any power source but notice that the supply voltage should be negative. There is a related line of 79xx devices which are complementary negative voltage regulators.

The LM78S40 from Fairchild is not part of the 78xx family and does not use the same design. January Learn how and when to remove this template message. The 78xx line are positive voltage regulators: Articles needing additional references from January All articles needing additional references. Meaning it will provide a constant output voltage of V when the input voltage is between A very basic Voltage regulator circuit is shown below.
