LK112M21TR Product Details

LK112M21TR Overview


The package is delivered in a Tape & Reel (TR) case. In order to package the IC voltage regulator, a SC-74A, SOT-753 case is used. On the Voltage regulator IC, there are 5 terminations that can be connected. This IC Regulator has a type of output called Fixed. There are 1 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 -30°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 5 pins. The regulator has a total of 1 outputs to make sure that it delivers prompt, sufficient outputs. Depending on the chip, 5 pins may be available. For your information, part number LK112 is the basic part number for this voltage regulator IC. There is a TAPE AND REEL way of packing the IC voltage regulators in the box.
