LP8728QSQE-A/NOPB Product Details
LP8728QSQE-A/NOPB Overview
optimized performance is achieved by utilizing the Tape & Reel (TR) package in this voltage regulator. A voltage regulator consists of 28 terminations. The type of analog IC that this voltage regulator is equipped with is POWER SUPPLY SUPPORT CIRCUIT. In order to save space, this voltage regulator is packaged in the 28-WFQFN Exposed Pad package. A total of 4 outputs are configured in this voltage regulator. The adjusting voltage regulator generates Fixed output. As the name implies, this voltage regulator 12v is designed for mounting on a Surface Mount bracket. As long as its operating temperature is -40°C~125°C TA, dc to dc voltage regulator should perform well. In this voltage regulator 12v, the switching frequency is 3.2MHz. Regulator 4.5V can operate with dc to dc voltage regulator's minimum input voltage 4.5V. DC DC switching regulator's output voltage (Min/Fixed) amounts to 1.25V 1.8V 1.8/2.65V 3.3V. Voltage regulators' input voltage is limited to 5.5V. This voltage regulator's peak reflow temperature is so high as to make it virtually indestructible. There is a subcategory called Switching Regulator or Controllers that includes this voltage regulator. In this case, the DC/DC regulator belongs to the family LP8728. At 3.3V volts, voltage regulator can provide voltage. 28 pins are used for switching regulator operation. The output voltage of this voltage regulator 12v should at least be set at 3.3V volts at all times. Accordingly, dc to dc voltage regulator's maximum output current is 1A A. As the name implies, this voltage regulator belongs to the Automotive, AEC-Q100 family of voltage regulators, and it is a type of switching DC-DC regulator. Voltage regulator consumes 1μA A of quiescent current without being affected by outside forces. This voltage regulator is suitable for running at a 5V V supply. This voltage regulator has 1 channels.
