LD2981ABU18TR Product Details

LD2981ABU18TR Overview


Deliveries are in Cut Tape (CT) cases. The package is in a TO-243AA case. Basically, the voltage regulator chip is made up of 3 terminations. This part implements 1 regulator ICs, which can be found in the following table. Regulator IC varies the range of Surface Mount operating temperatures. The Voltage Regulated IC operates at a temperature of -40°C~125°C degrees, which is its operating temperature. There is an output current of 100mA on this regulator. The total number of pins in the regulator is 3. This IC regulator has a total of 1 outputs, which ensures a rapid, adequate performance when in use. As an FYI, this IC voltage regulator has the basic part number LD2981. A FIXED POSITIVE SINGLE OUTPUT LDO REGULATOR regulator is the type of regulator that is used for this device. Packing the voltage regulator IC in this way is called TAPE AND REEL packing.
