LM3940ISX-3.3 Product Details

LM3940ISX-3.3 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-263-4, D2Pak (3 Leads + Tab), TO-263AA 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 -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 4. 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 3 axis. Here's the basic part number for this IC regulator: LM3940. Packing the voltage regulator IC is done in a method called TR. Upon reaching its maximal output current, 1A, it is able to satisfy the operation requirements. It operates in the 110μA Quiescent Current state.
