LT1521IST-3 Product Details

LT1521IST-3 Overview


A Bulk case is used to deliver the Voltage Regulated IC. A SOT-223 case is used for packaging. As you can see, the IC chip has 4 terminations. As far as its current output is concerned, it stands at 300mA. 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. The temperature should be below 125°C when you use the IC voltage regulator. There is no operating temperature below -40°C for the chip. With a supply current of 12μA, the regulator IC operates. In general, this IC voltage regulator is able to output 3V volts on a system basis.
