TPS79945YZUT Product Details

TPS79945YZUT Overview


A Tape & Reel (TR) case is used to deliver this IC regulator. This voltage regulator IC comes in a 5-UFBGA, DSBGA case. On the regulater IC chip, there are a total of 5 terminations. Output type Fixed. This component features 1 Voltage regulators. As a result of the Linear Voltage Regulator's design, the operating temperature of Surface Mount can be adjusted within a specified range. There is a temperature range of -40°C~125°C degrees during operation of the IC regulator. There is a configuration in this voltage regulator IC that specifies that its output function is Positive. In total, this chip consists of 5 pins and is divided into two groups. In order to deliver prompt, sufficient and reliable performance, this regulator IC has 1 outputs in total. A dropout voltage of 10 volts can be obtained from this voltage regulator IC. There are 5 pins on the chip. As an FYI, this IC voltage regulator has the basic part number TPS79945. As you can see from the picture, the regulator IC is packed in a certain way. Taking into account the operation requirements, the maximum output current of the IC voltage regulator reaches 200mA. It operates in the 40μA Quiescent Current state.
