LM317T-DG Product Details

LM317T-DG Overview


A Tube case is used to deliver the Voltage Regulated IC. A TO-220-3 case is used for packaging. As you can see, the IC chip has 3 terminations. Regulator IC chip's output type is Adjustable. The electronic part implements 1 regulators in total. In this Regulator IC chip, the operating temperature of Through Hole varies. 0°C~125°C degrees is the operating temperature of the Voltage Regulator IC. There is one output function configured for this voltage regulator IC, and that is Positive. As far as its current output is concerned, it stands at 1.5A. There are 3 pins in total in this voltage regulator IC. It has 1 outputs to ensure that the performance of this regulator is prompt and sufficient. 3 pins are on the chip. For your information, this regulator's basic part number is LM317. There is a way of packing the regulator that is called TAPE AND REEL. To meet operation requirements, the voltage regulator IC has a maximum output current of 400mA.
