KA7918TU Product Details

KA7918TU Overview


The package is delivered in a Tube case. In order to package the IC voltage regulator, a TO-220-3 case is used. On the Voltage regulator IC, there are 3 terminations that can be connected. This IC Regulator has a type of output called Fixed. There are 1 regulators implemented in this electroic component. Through Hole can be adjusted in the Linear IC in order to vary the temperature range over which Linear Regulator operates. The IC voltage regulator must be maintained at 0°C~125°C degrees for it to function. As you can see, this regulator's output function is configured to be Negative. At present, it can produce an output of up to 1A. The regulator has a total of 1 outputs to make sure that it delivers prompt, sufficient outputs. A dropout voltage of 10 volts is what makes it a dropout voltage. For your information, part number KA7918 is the basic part number for this voltage regulator IC. There is a RAIL way of packing the IC voltage regulators in the box. It operates in the 6mA Quiescent Current state.
