BA09ST Product Details

BA09ST Overview


The package is delivered in a Tube case. In order to package the IC voltage regulator, a TO-220-5 Full Pack case is used. On the Voltage regulator IC, there are 5 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 -40°C~85°C degrees for it to function. As you can see, this regulator's output function is configured to be Positive. At present, it can produce an output of up to 1A. A total of 3 pins are located on this chip, making it the size of a standard chip. 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 BA09 is the basic part number for this voltage regulator IC.
