RT7257CLZSP Product Details

RT7257CLZSP Overview


A Cut Tape (CT) package is used in this voltage regulator to optimize performance. During the development of this harley voltage regulator, 8 terminations were made. Space savings are achieved by placing this voltage regulator in the 8-SOIC (0.154, 3.90mm Width) Exposed Pad package. The voltage regulator is configured with 1 outputs. There are output pins on this DC DC switching regulator that generate Adjustable output. The voltage regulator 12v fits the Surface Mount mounting hole. Keeping dc to dc voltage regulator's operating temperature at -40°C~85°C TA is essential when operating. There is a switching frequency of 340kHz for this voltage regulator 12v. Voltage regulators like this one can operate at least with 4.5V as the dc to dc voltage regulator's minimum input voltage. DC DC switching regulator's output voltage (Min/Fixed) amounts to 0.8V. The output current of 3A makes dc to dc voltage regulator feature maximum design flexibility. The maximum input voltage of voltage regulator is 18V. In terms of category, this voltage regulator 12v falls into the Switching Regulator or Controllers category. 15V's maximal output voltage allows adjusting voltage regulator to operate easily.
