LD3985J25R Product Details

LD3985J25R Overview


The package is delivered in a Tape & Reel (TR) case. In order to package the IC voltage regulator, a 5-WFBGA, FCBGA case is used. On the Voltage regulator IC, there are 5 terminations that can be connected. 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. At present, it can produce an output of up to 150mA. As you can see, the regulator IC has a total of 5 pins. The regulator has a total of 1 outputs to make sure that it delivers prompt, sufficient outputs. A dropout voltage of 10 volts is what makes it a dropout voltage. Depending on the chip, 5 pins may be available. For your information, part number LD3985 is the basic part number for this voltage regulator IC. There is a TAPE AND REEL way of packing the IC voltage regulators in the box. There is a maximum output current of 550mA for this regulator to meet the operational requirements. It operates in the 150μA Quiescent Current state.
