    Products Detail

    L4949EPTR-E 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 20-SOIC (0.295, 7.50mm Width) case. The PMIC chip has 20 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 sum of the pins in this unit is 20. 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 20 axis. Here's the basic part number for this IC regulator: L4949. This voltage regulator IC is what is known as a standard Other Regulators component. Packing the voltage regulator IC is done in a method called TAPE AND REEL. Upon reaching its maximal output current, 100mA, it is able to satisfy the operation requirements. It operates in the 300?A Quiescent Current state. The phone is a member of the Automotive, AEC-Q100 Series.
