LP2951-33DR Product Details

LP2951-33DR Overview


Deliveries are in Tape & Reel (TR) cases. The package is in a 8-SOIC (0.154, 3.90mm Width) case. Basically, the voltage regulator chip is made up of 8 terminations. In this case, Adjustable (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~125°C TJ degrees, which is its operating temperature. It is configured for output function Positive on this regulator. The chip consists of a total of 8 pins in total. 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 8-shaped. As an FYI, this IC voltage regulator has the basic part number LP2951. Packing the voltage regulator IC in this way is called TR packing. The maximal output current reaches 100mA to meet the operating requirements. It operates in the 75μA Quiescent Current state.
