Description: Chinese LM7808 L7808CV L7808 7808 8V 1.5A Voltage Regulator IC 3 Pin TO-220 Package Fixed 8V Positive Voltage Regulator IC Chip
The LM78XX series of three terminal regulators is available with several fixed output voltages making them useful in a wide range of applications. One of these is local on card regulation, eliminating the distribution problems associated with single point regulation. The voltages available allow these regulators to be used in logic systems, instrumentation, HiFi, and other solid state electronic equipment. Although designed primarily as fixed voltage regulators these devices can be used with external components to obtain adjustable voltages and currents.
The LM78XX series is available in an aluminum TO-3 package which will allow over 1.0A load current if adequate heat sinking is provided. Current limiting is included to limit the peak output current to a safe value. Safe area protection for the output transistor is provided to limit internal power dissipation. If internal power dissipation becomes too high for the heat sinking provided, the thermal shutdown circuit takes over preventing the IC from overheating.
Considerable effort was expanded to make the LM78XX series of regulators easy to use and minimize the number of external components. It is not necessary to bypass the output, although this does improve transient response. Input bypassing is needed only if the regulator is located far from the filter capacitor of the power supply. For output voltage other than 5V, 12V and 15V the LM117 series provides an output voltage range from 1.2V to 57V.

Replacement and Equivalent / Other Part Numbers:
LM340T-06, LM340AT-6.0 voltage regulators can be used in the place of LM7808. But if you can’t find these alternative ICs then you can also use an LM317 as a 8V fixed output voltage regulator by adjusting the variable resistor on 8V output. All the guide for LM317 IC can be found online.
How to Safely Long Run in a Circuit:
To reliably run LM7808 IC for long life in your circuits you must use a suitable heatsink with the IC, do not exceed the input voltage from 35V DC, do not drive load of more than 1.5A through this IC and do not operate below 0 centigrade and above +125 centigrade and always store in temperature between -65 to +150 centigrade.
