LM3940LD-3.3/NOPB Product Details

LM3940LD-3.3/NOPB Overview


A Tape & Reel (TR) case is used to deliver the Voltage Regulated IC. A 8-WDFN Exposed Pad case is used for packaging. As you can see, the IC chip has 8 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~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 1A. 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. 8 pins are on the chip. For your information, this regulator's basic part number is LM3940. There is a way of packing the regulator that is called TAPE AND REEL. It operates in the 15mA Quiescent Current state.
