LD3985J48R Product Details

LD3985J48R Overview


The package is delivered in a Tape & Reel case. On the Voltage regulator IC, there are 5 terminations that can be connected. This IC Regulator has a type of output called Fixed. 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. As you can see, this regulator IC represents a typical Other Regulators component. 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. As a general rule, it is recommended that you use the IC voltage regulator when temperatures are below 125°C degrees Celsius. At the lowest operating temperature that can be reached by the chip, it is -40°C. Generally, this voltage regulator IC can output 4.8V volts on a system level.
