The Input and output capacitors C1 10uF and C2 1uF are used to filter noise from the input and the output voltage respectively.

LM Hoja de datos ( Datasheet PDF ) – 3 TERMINAL 1A NEGATIVE VOLTAGE REGULATOR

A very basic Voltage regulator circuit is shown below. Views Read Edit View history. The 78xx line are positive voltage regulators: January Learn how and when to remove this template message. Please help improve this article by adding citations to reliable sources. This article needs datasheer citations for verification. The is the most common, as its regulated 5-volt supply provides a convenient power source for most TTL components. Available in TO package only.

From Wikipedia, the free encyclopedia. The negative output voltage is obtained from the Vo datasueet Pin which is also read using a Multimeter. The LM78S40 from Fairchild is not part of the 78xx family and does not use the same design.

The circuit diagram for those can be found at the datasheet given at the end of this page. Encyclopedia of Electronic Components Volume 1: Meaning it will provide a constant output voltage of V when the input voltage is between Cool Projects for Open Source Hardware.

There is a related line of 79xx lm79912 which are complementary negative voltage regulators.

Retrieved from ” https: These devices support an input voltage anywhere from around 2. 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.

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. Datasheer are many other ways in which the IC can be used based on your application.

In other projects Wikimedia Commons. It is a component in switching regulator designs and is not a linear regulator like other 78xx devices. When you datwsheet 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. LM Applications Constant V output regulator to use as power or reference voltage for analog and digital circuits. Xatasheet output current of this IC is upto 1A, however with appropriate heat sink the datasheet says that a peak current of 2.
