RT7257GHZSP Product Details

RT7257GHZSP Overview


optimized performance is achieved by utilizing the Tape & Reel (TR) package in this voltage regulator. Throughout this voltage regulator, there are 8 terminations. The space-saving 8-SOIC (0.154, 3.90mm Width) Exposed Pad package is available for this voltage regulator. The voltage regulator 12v has 1 outputs. The adjusting voltage regulator generates Adjustable output. As the name implies, this voltage regulator 12v is designed for mounting on a Surface Mount bracket. During switching regulator operation, the operating temperature should remain at -40°C~85°C TA. This voltage regulator 12v reaches a switching frequency of 800kHz. The regulator is capable of operating with a dc to dc voltage regulator's minimum input voltage of 4.5V. As shown in the table below, adjusting voltage regulator's output voltage (Min/Fixed) is equal to 0.8V. A maximum design flexibility is provided by the 3A output current of voltage regulator. There is a maximum input voltage of 18V for this voltage regulator 12v. In terms of category, this voltage regulator 12v falls into the Switching Regulator or Controllers category. A voltage of 12V volts can be generated by DC DC switching regulator. There are 8 pins used for switching regulator operation. For this switching regulator, we recommend keeping the output voltage at at least 800mV volts. With a maximum output voltage of 12V, DC DC switching regulator has a very high efficiency.
