Is this actually true? It is a component in switching regulator designs and is not a linear regulator like other 78xx devices.

If one gives less than the proper voltage to an LM78XX type linear regulator, what do they do? That way you won’t have that extra series-pass loss. Call our Techstore on I’ll test it when mine arrives, but I asked here too: Sign up using Facebook. Post as a guest Name. Cool Projects for Open Source Hardware.

What do LM78XX type regulators do with low input voltage? If you don’t select insurance you are NOT insured. Views Read Edit View history. If you’re set lm7851 trying to run with lower voltage, I suggest connecting the regulated adapters to the output side of the 78XX regulators, not the input side.

These devices support an input voltage anywhere from around 2. Parcel Lockers We deliver to parcel lockers around Australia.

January Learn how and when to remove this template message. Additional delivery time may result for some deliveries. Please allow extra time for delivery to western states. What about for the LM? 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.

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. Most likely they will be ‘solidly’ on and not regulating whatsoever. This page was last edited on 5 Decemberat 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 A voltage regulator may use a simple feed-forward design or may include negative feedback.

For the years, see 8th millennium. Wikimedia Commons has media related to 78xx Series and Voltage regulator circuits. If shipping to a PO Box you must select standard delivery during checkout.

Home Questions Tags Users Unanswered. Premium freight is not available on oversized or bulky items. Some devices provide slightly different voltages than usual, such as the LM78L62 6. Please help improve this article by adding citations to reliable sources.

The is the most common, as its regulated 5-volt supply provides a convenient power source for most TTL components.

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. If I were to feed it 12, what would be the probable behavior?
