Arashigrel If I were to feed it 12, what would be the probable behavior? The internal feedback will detect that the output is too low and essentially saturate the series-pass element as much as it can meaning the output voltage will be less than the input, and unregulated. The 78xx line are positive voltage regulators: In other projects Wikimedia Commons. Or is lm going to do some oddball oscillating behavior? Additional delivery time may result for some deliveries. Please help improve this article by adding citations to reliable sources.

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, instrumenta- tion, HiFi, and other solid state electronic equipment. Al- though designed primarily as fixed voltage regulators these devices can be used with external components to obtain ad- justable voltages and currents.

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 dissi- pation. 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 se- ries of regulators easy to use and minimize the number of external components. It is not necessary to bypass the out- put, although this does improve transient response.

Input by- passing 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 LM series provides an output voltage range from 1.

Features Output current in excess of 1A n.
