LP3990TLX-2.8 Product Details

LP3990TLX-2.8 Overview


Basically, the voltage regulator chip is made up of 4 terminations. In this case, Fixed represents the output type of the Voltage Regulated IC. There is an output current of 150mA on this regulator. The total number of pins in the regulator is 4. This IC regulator has a total of 1 outputs, which ensures a rapid, adequate performance when in use. There is a voltage dropout of 10 volts for this IC regulator. Several pins on the chip are 4-shaped. It operates in the 80μA Quiescent Current state. Whenever the temperature is less than 85°C, it is recommended that you use it. The chip is operated at a maximum operating temperature of -40°C. As a general rule, this regulator IC outputs 2.8V volts on a system basis.
