Victor 884 voltage regulators
Does anyone know what type of voltage regulators are on the Victor 884?

Re: Victor 884 voltage regulators
If you are referring to the 9 things that LOOK like a 780x voltage regulator, they are actually a MOSFET, I believe... but I do not have the part number in front of me.
There are many different types of semiconductor devices that look similar to this, as the "package" is called a TO-220. So just as you have many different DIP IC's that look the same, you can also have many three-pinned parts that look the same. I take it you are planning to re-build a blown victor? Jason |

Re: Victor 884 voltage regulators
I don't know about the Victor 884, but the Victor 883 uses the 5V version of the LM2931 in an SOIC-8 package. They have a PIC16F627 doing the signal processing. The mosfets on the 883 are the IRL2203N. The high side gate voltage for the mosfets is generated by a simple boost regulator. Op amps are used to control the voltage going to the gates.
