L4940D2T12-TR Product Details

L4940D2T12-TR Overview


The package contains a Tape & Reel (TR) case. In TO-263-3, D2Pak (2 Leads + Tab), TO-263AB cases, it is packaged. This gadget has 2 terminations on it, each with a different function. Fixed is the IC Voltage Regulator's output type. A total of 1 regulators are implemented in this eletric component. Surface Mount operating temperature varies depending on the IC Voltage Regulator. The Regulator IC chip is set to operate at -40°C~150°C degrees. It has been configured that the output function of this IC regulator is Positive. 3 pins make up the sum of this IC voltage regulator. As a result of this IC voltage regulator's 1 outputs, it ensures prompt, adequate performance for all your applications. As far as its dropout voltage is concerned, it is 10 volts. The regulator IC has 3 pins. I just wanted to let you know that this IC voltage regulator has the part number L4940 as its basic part number. In this case, the IC voltage regulator will be packed in the following way. When operating at maximum output current, the regulator IC reaches 1.5A. It operates in the 8mA Quiescent Current state.
