LM2937IMPX-3.3/NOPB Product Details

LM2937IMPX-3.3/NOPB Overview


A Tape & Reel (TR) case is used to deliver the Voltage Regulated IC. A TO-261-4, TO-261AA case is used for packaging. As you can see, the IC chip has 4 terminations. Regulator IC chip's output type is Fixed. The electronic part implements 1 regulators in total. In this Regulator IC chip, the operating temperature of Surface Mount varies. -40°C~85°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. 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. The dropout voltage of the regulator IC is 10 volts. 4 pins are on the chip. For your information, this regulator's basic part number is LM2937. There is a way of packing the regulator that is called TR. To meet operation requirements, the voltage regulator IC has a maximum output current of 400mA. It operates in the 10mA Quiescent Current state.
