How to Connect a Voltage Regulator in a Circuit

Post as a guest Name. Alfred Centauri 24k 1 15 The demo board input range is 36V to 80V.

The package for this IC i. If we have a system with input 15 volts and output current required is.

Thank you for pointing it out Steve. To open the project file for this circuit: Ladislav 3 9. You can buy them at anytime and come back to this page and do the experiment.

Note that this does not accomplish the traditional meaning of “regulate” as the output voltage would vary with the input voltage and the load, instead of remaining stable as a “regulator” usually attempts to achieve. External Power Switch Buck-Boost.

All About IC | Voltage Regulator Pin Diagram & Schematics

Their website shows an example circuit as shown here, where R2 is your pot: Always consult the Manufacturer’s Datasheet for the voltage regulator in use for a circuit to see how to hook it up with the necessary required external components.


When you put the additional load away, the voltage would rise and the regulator closes the transistor, cutting the overvoltage away. Sir i made a voltage regulator using ic for powering my microcontroller but my chip isnt working Plz tell me where i m wrong. Most orders ship within 48 hours of this date.

I know that what I say is plenty wrong, and the circuit diagram is correct. Without the output capacitor, the regulator could oscillate even if no transients were introduced by the load. The product is appropriate for new designs but newer alternatives may exist.

Mr Bonjour 1 2 I know that when capacitors are in series, you add their values. International prices may differ due to local duties, taxes, fees and exchange rates.

How to Connect a Voltage Regulator in a Circuit

It is important to note the scheduled dock date on the order entry screen. However, for experimental purposes and ease of getting parts, we will use a 9-volt battery as our input voltage.

How can user edit this question with a reputation of 5? The LT is a high performance buck-boost switching regulator controller that operates from input voltages above, below or equal to the output voltage.

The voltage input is 5V. Download and install LTspice on your computer.

Hope it suits your requirements. It is used to eliminate the transients caused by the switching on the Totem Pole dataseet on the digital ICs that may be connected on the output. If you use Majenko’s method, you will get a linear relationship You can still determine what the resistance your pot is at, it will just require a little bit of math.


Click on the link in the section below to download a demonstration circuit. So I really don’t understand how you can use the smoothed output values, since in the circuit diagram, it seems that the direct output datashheet to the ground.

It would be good for you to include all of this information in your questions. This pin is neutral for equally the input and output.

Other models listed in the table may still be available if they have a status that is not obsolete. If there any circuit available please let me know the function of that circuit. The output voltage of whatever voltage source you want to regulate down whether it’s a transformer, battery, etc. The output is optimized for 48V at 5A, with the output current limit set at 7A. Recommended for all new designs. In fact if you were to plot it, it would look like so:.

This capacitor is there to filter out any noise coming from the voltage source the battery.
