For the years, see 8th millennium. Cool Projects for Open Source Hardware. 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 78xx line are positive voltage regulators: It is a component in switching regulator designs and is not a linear regulator like other 78xx devices.

Unsourced material may be challenged and removed. The value of the capacitors need not be the exact values, you can use the closest value you have got. Some devices provide slightly different voltages than usual, such as the LM78L62 6. I have used a Battery to power the IC, but you can use datasbeet power source but notice that the supply voltage should be negative.

The is the most common, as its regulated 5-volt supply provides a convenient power source for most TTL components. The output current of this IC is upto 1A, however with appropriate heat sink the datasheet says that a peak current of 2.

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. When you are designing an analog circuitthe circuit might need negative voltage either as a power source or as a reference voltage. Submitted by webmaster on 23 November The negative output voltage is obtained from the Vo 3rd 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 78xx family is commonly used in electronic circuits requiring a regulated power supply due to their ease-of-use and low cost. In both cases will be an ideal choice when you need datasheef negative 12V. From Wikipedia, the free encyclopedia. This page was last edited on 5 Decemberat Datxsheet devices support an input voltage anywhere from around 2.


Meaning it will provide a constant output voltage of V when the input voltage is between LM belongs to the family of Voltage regulators. Views Read Edit View history.
