LP3991TLX-1.2 Product Details

LP3991TLX-1.2 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 300mA 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. Several pins on the chip are 4-shaped. The maximal output current reaches 300mA to meet the operating requirements. It operates in the 50μA 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 1.2V volts on a system basis.
