LM3940IS-3.3 Product Details

LM3940IS-3.3 Overview


An Tube case is included with the delivery. There is a TO-263-4, D2Pak (3 Leads + Tab), TO-263AA case with the integrated voltage regulator. There are 3 terminations on the battery regulator IC chip and each of them has its own function. In terms of output type, Fixed is what the Regulator IC produces. The electronic component implements 1 Voltage regulator ICs. IC Regulator is possible to alter the range of the operating temperature of Surface Mount in the device. In order for this IC voltage regulator to operate, the temperature has to be kept at -40°C~125°C degrees. In this case, the output function that is configured for this regulator IC is Positive. It has a total of 4 pins on IC voltage regulator. In order to ensure prompt, adequate, and prompt performance, this regulator has 1 outputs in total. In terms of its dropout voltage, it is 10 volts. There are 3 pins on the chip. It is LM3940 for this regulator, just for your information. In order to meet the operating requirements of the regulator, its maximal output current reaches 1A. It operates in the 110μA Quiescent Current state.
