MC78L12ACPG Product Details

MC78L12ACPG Overview


The package is delivered in a Bulk case. In order to package the IC voltage regulator, a TO-226-3, TO-92-3 (TO-226AA) case is used. On the Voltage regulator IC, there are 3 terminations that can be connected. This IC Regulator has a type of output called Fixed. There are 1 regulators implemented in this electroic component. Through Hole 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 0°C~125°C degrees for it to function. As you can see, this regulator's output function is configured to be Positive. As you can see, the regulator IC has a total of 3 pins. The regulator has a total of 1 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, 3 pins may be available. For your information, part number MC78L12 is the basic part number for this voltage regulator IC. There is a maximum output current of 100mA for this regulator to meet the operational requirements. In regards to tolerance, this voltage regulator IC has an 5% tolerance, which is quite low.
