LD3985J47R Product Details

LD3985J47R Overview


A Tape & Reel case is used to deliver this IC regulator. On the regulater IC chip, there are a total of 5 terminations. Output type Fixed. In terms of its current output, it is able to supply 150mA. A total of 5 pins can be found on the board. In order to deliver prompt, sufficient and reliable performance, this regulator IC has 1 outputs in total. A dropout voltage of 10 volts can be obtained from this voltage regulator IC. There are 5 pins on the chip. An example of such a component would be this Other Regulators component. As you can see from the picture, the regulator IC is packed in a certain way. Taking into account the operation requirements, the maximum output current of the IC voltage regulator reaches 550mA. It operates in the 150μA Quiescent Current state. If the temperature is below 125°C, it is recommended that you utilize this feature. It is recommended that the chip be operated at a temperature no lower than -40°C operating temperature. As a result, this IC regulator will typically output 4.7V volts as a system.
