RT7257ALZSP Product Details

RT7257ALZSP Overview


This harley voltage regulator utilizes the Cut Tape (CT) package for optimized performance. As you can see, this harley voltage regulator contains 8 terminations. Space-saving 8-SOIC (0.154, 3.90mm Width) Exposed Pad packages are available for this harley voltage regulator. The voltage regulator 12v has 1 outputs. The adjusting voltage regulator generates Adjustable output. Surface Mount-mounting is compatible with this switching regulator. This voltage regulator 12v should operate at a temperature of -40°C~85°C TA when operating. DC-DC switching regulators reach 340kHz switching frequencies. The regulator is capable of operating with a dc to dc voltage regulator's minimum input voltage of 4.5V. The adjusting voltage regulator's output voltage (Min/Fixed) is 0.8V. Featuring a maximum design flexibility of 3A, dc to dc voltage regulator has a maximum output current of 3A. Voltage regulator's input voltage can reach 18V. In terms of category, this voltage regulator 12v falls into the Switching Regulator or Controllers category. There are 8 pins used for switching regulator operation. In order for this switching regulator to work properly, the output voltage should be at least 800mVV. Using this voltage regulator 12v, you will be able to get the maximum output voltage of 15V.
