LF55CDT-TR Product Details

LF55CDT-TR Overview


The package is in a TO-252 case. Basically, the voltage regulator chip is made up of 2 terminations. In this case, Fixed represents the output type of the Voltage Regulated IC. There is an output current of 1A 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. There is a voltage dropout of 10 volts for this IC regulator. Several pins on the chip are 3-shaped. An example of this type of component would be a Other Regulators component. Packing the voltage regulator IC in this way is called TAPE AND REEL packing. The maximal output current reaches 1A to meet the operating requirements. It operates in the 1mA Quiescent Current state. Whenever the temperature is less than 125°C, it is recommended that you use it. The chip is operated at a maximum operating temperature of -40°C. As a general rule, this regulator IC outputs 5.5V volts on a system basis.
