KA278RA05CTU Product Details

KA278RA05CTU Overview


An Tube case is included with the delivery. There is a TO-220-4 Full Pack case with the integrated voltage regulator. There are 4 terminations on the battery regulator IC chip and each of them has its own function. In terms of output type, Adjustable (Fixed) is what the Regulator IC produces. The electronic component implements 1 Voltage regulator ICs. IC Regulator is possible to alter the range of the operating temperature of Through Hole in the device. In order for this IC voltage regulator to operate, the temperature has to be kept at -20°C~80°C degrees. In this case, the output function that is configured for this regulator IC is Positive. In order to ensure prompt, adequate, and prompt performance, this regulator has 1 outputs in total. In terms of its dropout voltage, it is 10 volts. There are 4 pins on the chip. It is KA278RA05 for this regulator, just for your information. In order to pack the regulator, the method is RAIL. In order to meet the operating requirements of the regulator, its maximal output current reaches 2A. It operates in the 10mA Quiescent Current state.
