    Products Detail

    L4957AD1.8TR 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 TO-263-3, D2Pak (2 Leads + Tab), TO-263AB case. The PMIC chip has 3 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 0°C~125°C degrees is necessary for this regulator to function. There is an output function of Positive configured for this regulator. Currently, 5A are being output by it at the moment. The chip has a total of 3 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. Here's the basic part number for this IC regulator: L4957. 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.
