RT7257CHZSP Product Details

RT7257CHZSP Overview


This harley voltage regulator utilizes the Cut Tape (CT) package for optimized performance. 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 of voltage regulator are configured. Adjusting voltage regulator's output pins generate Adjustable output. Surface Mount-mount switching regulator. When operating, adjusting voltage regulator's operating temperature should be kept at -40°C~85°C TA. This DC-DC switching regulator has a switching frequency of 340kHz. The voltage regulator can operate with a dc to dc voltage regulator's minimum input voltage of 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. As far as the voltage input is concerned, DC DC switching regulator can accept up to 18V. A voltage regulator 12v such as this falls under the Switching Regulator or Controllers category and belongs to this category. By using the 15V's maximal output voltage, adjusting voltage regulator can operate easily.
