    Products Detail

    LDK120PU18R Overview


    The package is delivered in a Tape & Reel (TR) case. In order to package the IC voltage regulator, a 6-XFDFN case is used. This IC Regulator has a type of output called Fixed. There are 1 regulators implemented in this electroic component. Surface Mount 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~125°C degrees for it to function. As you can see, this regulator's output function is configured to be Positive. A dropout voltage of 10 volts is what makes it a dropout voltage. Depending on the chip, 6 pins may be available. For your information, part number LDK120 is the basic part number for this voltage regulator IC. There is a maximum output current of 200mA for this regulator to meet the operational requirements. It operates in the 60μA Quiescent Current state. In order for it to operate, a supply current of 50μA must be applied.
