L4947R Product Details

L4947R Overview


There are 5 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. There is an 500mAmp current output on this voltage regulator IC. It has a total of 5 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 5 pins on the chip. In order to meet the operating requirements of the regulator, its maximal output current reaches 500mA. It operates in the 10mA Quiescent Current state. Utilize the regulator IC when the temperature is below 125°C. It is recommended that the chip be operated at a temperature no lower than -40°C operating temperature. According to its specs, this IC voltage regulator generally outputs 5V volts.
