LM Applications Constant V output regulator to use as power or reference voltage for analog and digital circuits. In other projects Wikimedia Commons.

Please help improve this article by adding citations to reliable sources. 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.

The Input and output datxsheet C1 10uF and C2 1uF are used to filter noise from the input and the output voltage respectively. By using this site, you agree to the Terms of Use and Privacy Policy.

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 datawheet 78xx ICs. When you are designing an analog circuitthe circuit might need negative voltage either as a power source or as a reference voltage.

Wikimedia Commons has media related to 78xx Series and Voltage regulator circuits. LM belongs to the family of Voltage regulators. The LM78S40 from Fairchild is not part of the 78xx family and does not use the same design. It is a component in switching regulator designs and is not a linear regulator like other 78xx devices.

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. There is a related line of 79xx devices which are complementary negative voltage regulators. The circuit diagram for those can be found at the datasheet given at the end of this page.

Submitted by webmaster on 23 November This page was last edited on 5 Decemberat Mastering the Raspberry Pi. The negative output voltage is obtained from the Vo 3rd Pin which is also read using a Multimeter.

You can also check on 78 lm7192 for positive voltage regulators. The 78xx family is commonly used in electronic circuits requiring a regulated power supply due to their ease-of-use and low cost. The is the most common, as its regulated 5-volt supply provides a convenient power source for most TTL components.

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