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.

What do LM78XX type regulators do with low input voltage? This page was last edited on 5 Decemberat From Wikipedia, the free encyclopedia. January Learn how and when to remove this template message. The specific circuit in question normally has 22 volts feeding the input of an LM the data sheet lists the minimum Vin for this part at The is the most common, as its regulated 5-volt supply provides a convenient power source for most TTL components.

Industrial Electronics and Control. It has plot for Dropout characteristics. The 78xx family is commonly used in electronic circuits requiring a regulated power supply due to their ease-of-use and low cost. The Dataheet from Datel is a full switching power supply module designed as a drop-in replacement for 78xx chipsand not a datashete regulator like the 78xx ICs.

LM7815 Datasheet and LM7815 manual

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.
