LM7810 Description:

LM7810 is a positive voltage regulator IC, it is an IC of LM78xx series that is a series of positive voltage regulators. The IC provides accurate 10V at the output with 1A to 1.5A output current but a proper heatsink will be required to get 1A or 1.5A current from the IC. The IC can handle maximum input voltage of upto 35V.

One of a good feature of these voltage regulators is that whether the input voltage is constantly changing between 13V to 35V the output of the IC will be remain 10V. To get accurate 10V output with the IC the input voltage must be 3 to 4 volt higher than the output voltage.

LM7810 is also a reliable IC to use in commercial appliances and equipment its built in short circuit protection, overheat protection and safe area protection functions makes it internally damage proof so it can provide long term performance in circuits.

How to Safely Long Run in a Circuit:

To get good and stable performance for long life with this IC it is suggested to not drive load of more than 1.5A with the IC, always use a suitable heatsink, do not apply input voltage more than 35V for more safety do not provide input voltage more than 25V to 30V. When in operation the temperature around the IC should be above 0 degree centigrade and below +125 degree centigrade, and the storing temperature should be maintained in between -65 degree Celsius to +150 degree Celsius.
