LDS3985M33R Product Details

LDS3985M33R Overview


In the case of Tape & Reel (TR) cases, the regulater IC is delivered. Packaging of the Liner regulator IC takes the form of a SC-74A, SOT-753 case. The PMIC chip has 5 terminations. Fixed is the Voltage Regulator Chip's output type. Linear IC consists of 1 battery regulators. The range of operating temperatures of Surface Mount are programmable in the Voltage Regulator Chip, so that the temperature can be varied as desired. Keeping the temperature at -40°C~125°C degrees is necessary for this regulator to function. There is an output function of Positive configured for this regulator. The chip has a total of 5 pins on it, each with its own function. The part includes 1 outputs in order to ensure that the voltage regulator IC performs effectively and in a timely manner. This voltage regulator IC has a dropout voltage of 10 volts. On the chip, there are pins for the 5 axis. Here's the basic part number for this IC regulator: LDS3985. Packing the voltage regulator IC is done in a method called TAPE AND REEL. Upon reaching its maximal output current, 300mA, it is able to satisfy the operation requirements. It operates in the 150μA Quiescent Current state.
