BU31TA2WNVX-TR Product Details

BU31TA2WNVX-TR Overview


Deliveries are in Tape & Reel (TR) cases. The package is in a 4-UDFN Exposed Pad case. Basically, the voltage regulator chip is made up of 4 terminations. In this case, Fixed represents the output type of the Voltage Regulated IC. This part implements 1 regulator ICs, which can be found in the following table. Regulator IC varies the range of Surface Mount operating temperatures. The Voltage Regulated IC operates at a temperature of -40°C~85°C degrees, which is its operating temperature. It is configured for output function Positive 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. As an FYI, this IC voltage regulator has the basic part number BU31TA2. Packing the voltage regulator IC in this way is called TAPE AND REEL packing. The maximal output current reaches 200mA to meet the operating requirements.
