LM2940IMPX-12 Product Details

LM2940IMPX-12 Overview


An Tape & Reel (TR) case is included with the delivery. There is a TO-261-4, TO-261AA 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~85°C degrees. In this case, the output function that is configured for this regulator IC is Positive. There is an 1Amp current output on this voltage regulator IC. 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 4 pins on the chip. It is LM2940 for this regulator, just for your information. In this instance, we are dealing with a typical Other Regulators-shaped component. In order to pack the regulator, the method is TAPE AND REEL. It operates in the 15mA Quiescent Current state.
