There is a related line of 79xx devices which are complementary negative voltage regulators. 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.


Unsourced material may be challenged and removed. The specific circuit in question normally has 22 volts feeding dxtasheet input of an LM the data sheet lists the minimum Vin for this part at Cool Projects for Open Source Hardware.

If I were to feed it 12, what would be the probable behavior? From Wikipedia, the free encyclopedia. Additional delivery time may result for some deliveries. Michael Kohne 2, 12 Some devices provide slightly different voltages than usual, such as the LM78L62 6.

7815 Voltage Regulator Fixed Positive 15V Linear IC L7815CV

I’m well aware that there are no guarantees once you violate the specs given in the data sheet, but I’m analyzing something that someone else did, and I want to make sure of what it’s doing before I risk boards on it. Sign up using Facebook. Call our Techstore on For the years, see 8th millennium. Please allow extra time for delivery datashest western states.

LM7815 Positive +15v Voltage Regulator

If one gives less than the proper voltage to an LM78XX type linear regulator, what do they do? What about for the LM? Most likely they will be ‘solidly’ on and not regulating whatsoever.

Be the first to know about our newest products, specials and promotions: In other projects Wikimedia Commons. Premium freight is not available on oversized or bulky items. 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 daatasheet than the input, and unregulated. Please contact us if you need to check whether Next Day delivery applies to your area The is the most common, as its regulated 5-volt supply provides a convenient power source for most TTL components.


The LM78S40 from Fairchild is not part of the 78xx family and does not use the same design.

What do LM78XX type regulators do with low input voltage? – Electrical Engineering Stack Exchange

A voltage regulator may use a simple feed-forward design or may datssheet negative feedback. It is a component in switching regulator designs and is not a linear regulator like other 78xx devices. Retrieved from ” https: I’d like to understand why that might work, before I go plugging things up. It has plot for Dropout characteristics.
