L4947PD Product Details

L4947PD Overview


An Tube case is included with the delivery. There is a 20-SOIC (0.433, 11.00mm Width) Exposed Pad case with the integrated voltage regulator. There are 20 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. There is an 500mAmp current output on this voltage regulator IC. It has a total of 20 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 20 pins on the chip. It is L4947 for this regulator, just for your information. It operates in the 10mA Quiescent Current state.
