LD3985J31R 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 150mAmp 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. 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. 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 3.1V volts.
