In summary,You need a 5-volt regulator (78L05), a hall sensor (SS495), an op-amp (LM348), and a P-channel MOSFET (IRF4905). You can get these parts from a variety of places, such as Mouser.

I need a 5-volt regulator (78L05), a hall sensor (SS495), an op-amp (LM348), and a P-channel MOSFET (IRF4905)? I need all these things for a magnetic levitron that I'm going to build. Do I have to get those exact models? (They are specified on the website that has the circuit scheme for it http://www.bis0uhr.de/index.htm?htt...sicsforums.com/showthread.php?t=643270&page=3).
Thanks for your help
PS. Just so you know, I'm very new at all of this, so forgive me if all the things I'm asking are really obvious.

hi there :)

the parts should be readily available from places like Mouser, Digikey, Element14 etc

the 78L05 needs to be that else you won't get 5 Volts the difference between 78L05 and 7805 is just the package size

the opamp could probably be varied a bit, the 741 is a very old one now the 348 a bit newer

cheers

Thanks very much, that's exactly the info I needed. Is mouser a reliable site?

Also, the IRF4905 isn't available. Would the IRF4905LPBF be OK? What difference does the LPBF make?

The part IRF4905LPbF is a HEXFET power mosfet transistor. Download the eleven-page data sheet at:

http://www.alldatasheet.com/datasheet-pdf/pdf/177507/IRF/IRF4905LPBF.html

Your part number suffix is for the TO-262 Package type. For a description of that see page ten of the datasheet.

You should print the complete datasheet and study it carefully. Everything about that part you need to know is there. This helps your understanding and makes it easier in the future while selecting parts for your next projects.

Cheers,

edit: Yes, Mouser is a reliable site to buy parts from. It's been around many years!
 

FAQ: Where can I find regulators and more?

Where can I find regulators and more?

Regulators and other scientific equipment can be found at specialized scientific supply stores, online retailers, and sometimes even at hardware stores. It is important to do thorough research and compare prices before making a purchase.

What types of regulators are available?

There are various types of regulators used in different scientific fields, such as pressure regulators, temperature regulators, flow regulators, and pH regulators. It is important to understand the specific needs of your experiment or study before choosing a regulator.

Can I use a regulator for different types of experiments?

Some regulators are versatile and can be used for different types of experiments, while others are designed for specific purposes. It is important to read the product specifications and instructions carefully to ensure that the regulator is suitable for your experiment.

How do I know if a regulator is of good quality?

When purchasing a regulator, look for reputable brands and check for certifications or accreditations. It is also helpful to read reviews and ask for recommendations from other scientists or colleagues who have used the same type of regulator.

Can I make my own regulator?

It is not recommended to make your own regulator unless you have extensive knowledge and experience in designing and building scientific equipment. Improperly made regulators can be dangerous and may not provide accurate results. It is best to purchase a regulator from a trusted source.
