BA178M18FP-E2 Product Details

BA178M18FP-E2 Overview


A Tape & Reel (TR) case is used to deliver the Voltage Regulated IC. A TO-252-3, DPak (2 Leads + Tab), SC-63 case is used for packaging. As you can see, the IC chip has 2 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 4 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. 3 pins are on the chip. For your information, this regulator's basic part number is BA178M. 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 500mA.
