    Products Detail

    L4938EPD Overview


    The package is delivered in a Tube case. In order to package the IC voltage regulator, a 20-SOIC (0.433, 11.00mm Width) Exposed Pad case is used. On the Voltage regulator IC, there are 20 terminations that can be connected. This IC Regulator has a type of output called Adjustable (Fixed). There are 2 regulators implemented in this electroic component. Surface Mount can be adjusted in the Linear IC in order to vary the temperature range over which Linear Regulator operates. The IC voltage regulator must be maintained at -40°C~150°C degrees for it to function. As you can see, this regulator's output function is configured to be Positive. At present, it can produce an output of up to 100mA 400mA. As you can see, the regulator IC has a total of 20 pins. The regulator has a total of 2 outputs to make sure that it delivers prompt, sufficient outputs. A dropout voltage of 10 volts is what makes it a dropout voltage. Depending on the chip, 20 pins may be available. For your information, part number L4938 is the basic part number for this voltage regulator IC. As you can see, this regulator IC represents a typical Other Regulators component. It operates in the 20mA Quiescent Current state.
