    Products Detail

    LD3985M18R Overview


    Cut Tape (CT) cases are used for delivery. The Liner regulator IC is packaged in SC-74A, SOT-753 case. On the Linear IC itself, there are 5 terminations. Fixed is the output type of the Voltage Regulator IC. As part of this electrical component, 1 regulators are implemented. Variations are made to the Surface Mount operating temperature range by the Voltage Regulator IC. Default settings are set to -40°C~125°C degrees. There is a Positive configured as the output function for this IC regulator. There is a current output of 150mA from this regulator IC. There are a total of 5 pins on this board. There are 1 outputs total on this voltage regulator IC in order to ensure that prompt and sufficient performance is achieved. There is a dropout voltage of 10 volts on this IC regulator. Chips have 5 pins. For your information, the basic part number for this regulator IC is LD3985. In this case, we have a typical Other Regulators component. TAPE AND REEL is the way in which the voltage regulator IC is packed. In order to meet the operation requirements, its maximal output current reaches 550mA. It operates in the 150?A Quiescent Current state.
