KA78M12TU Product Details

KA78M12TU Overview


In the case of Tube cases, the regulater IC is delivered. Packaging of the Liner regulator IC takes the form of a TO-220-3 case. Fixed is the Voltage Regulator Chip's output type. Linear IC consists of 1 battery regulators. The range of operating temperatures of Through Hole are programmable in the Voltage Regulator Chip, so that the temperature can be varied as desired. Keeping the temperature at 0°C~125°C degrees is necessary for this regulator to function. There is an output function of Positive configured for this regulator. Currently, 500mA are being output by it at the moment. The part includes 1 outputs in order to ensure that the voltage regulator IC performs effectively and in a timely manner. This voltage regulator IC has a dropout voltage of 10 volts. Here's the basic part number for this IC regulator: KA78M12. It operates in the 6mA Quiescent Current state. In the event that the temperature in your room falls below 125°C, then this feature should be used at such a time. During the operation of the chip, the chip's operating temperature is not less than 0°C degrees.
