So where is the thing coming from? Nov 9, 5, Ok I think I follow you drift. By using this site, you agree to the Terms of Use and Privacy Policy. Nov 23, 8, 6, The regulation may be less than perfect if the regulator was open circuit using – but why would that matter?

Higher regulated voltages are obtained by connecting the adjustment pin to a resistive voltage divider between the output and ground. Archived from the original on 17 December Aug 20, 2. This page was last edited on 6 Julyat Aug 20, 8.


The alternative is to use a switching voltage regulator which is usually more efficient but has a larger footprint and requires a larger number of associated components. The output current is that resulting from dropping the reference voltage across the resistor. The LM relates in the same way to the fixed 79xx regulators. The LM is a popular adjustable positive linear voltage regulator. Wikimedia Commons has media related to LM and Voltage regulator circuits.

Like the LM, each of the 78xx regulators is designed to adjust the output voltage until it is some fixed voltage above the adjustment pin which in this case is labelled ” ground “.

For large voltage differences, the energy lost as heat can ultimately be greater than that provided to the circuit. It was designed by Robert “Bob” Pease.

The mechanism used is similar enough datsheet a voltage divider can be used in the same way as with the LM and the output follows the same formula, using the regulator’s fixed voltage for V ref e. Accidenti come scotta questo transistor. Jan 24, Failure to do this may cause the circuit to short. Help me understand this. I think I now understand the LM as well as I ever will. Feb 13, 1, The device can be configured to regulate the current to a load, rather than the voltage, by replacing the low-side resistor of the divider with the load itself.
