RT7257BLZSP Product Details
RT7257BLZSP Overview
Using the Cut Tape (CT) package, this voltage regulator optimizes the performance of the voltage regulator 12v. A voltage regulator consists of 8 terminations. There is a 8-SOIC (0.154, 3.90mm Width) Exposed Pad package available for this voltage regulator, as DC DC switching regulator is space-saving. 1 outputs have been configured in the voltage regulator 12v. On its output pins, this adjusting voltage regulator generates Adjustable output. Switching regulators like this one can be mounted on the Surface Mount mounting system. In order for it to operate properly, dc to dc voltage regulator's operating temperature should be at -40°C~85°C TA. In this voltage regulator 12v, the switching frequency is 1.2MHz. Regulator 4.5V can operate with dc to dc voltage regulator's minimum input voltage 4.5V. There is a adjusting voltage regulator's voltage output (Min/Fixed) of 0.8V. DC DC switching regulator's maximum design flexibility comes from its output current of 3A. Voltage regulator's input voltage can reach 18V. There is a subcategory of this regulator voltage called Switching Regulator or Controllers. In order to operate voltage regulator, 8 pins are required. This voltage regulator 12v should be configured with an output voltage that is at least 800mV. Using this voltage regulator 12v, you will be able to get the maximum output voltage of 12V.
