LM2940IMP-12/NOPB Product Details

LM2940IMP-12/NOPB Overview


Deliveries are in Cut Tape (CT) cases. The package is in a TO-261-4, TO-261AA 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. There is a voltage dropout of 10 volts for this IC regulator. Several pins on the chip are 4-shaped. As an FYI, this IC voltage regulator has the basic part number LM2940. Packing the voltage regulator IC in this way is called TR packing. The maximal output current reaches 1A to meet the operating requirements. It operates in the 15mA Quiescent Current state. The top supply voltage can be set to 26V volts.
