LD3985M30R Product Details

LD3985M30R Overview


A Tape & Reel (TR) case is used to deliver this IC regulator. This voltage regulator IC comes in a SC-74A, SOT-753 case. On the regulater IC chip, there are a total of 5 terminations. Output type Fixed. This component features 1 Voltage regulators. As a result of the Linear Voltage Regulator's design, the operating temperature of Surface Mount can be adjusted within a specified range. There is a temperature range of -40°C~125°C degrees during operation of the IC regulator. There is a configuration in this voltage regulator IC that specifies that its output function is Positive. 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. As an FYI, this IC voltage regulator has the basic part number LD3985. 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. 3% tolerance is what this regulator IC has, which is quite low.
