RT4803WSC Overview
optimized performance is achieved by utilizing the Cut Tape (CT) package in this voltage regulator. The space-saving 16-UFBGA, WLCSP 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 2.5MHz. The regulator is capable of operating with a dc to dc voltage regulator's minimum input voltage of 1.8V. As shown in the table below, adjusting voltage regulator's output voltage (Min/Fixed) is equal to 2.85V. A maximum design flexibility is provided by the 2A Switch output current of voltage regulator. There is a maximum input voltage of 5V for this voltage regulator 12v. A voltage of 4.4V volts can be generated by DC DC switching regulator. There are 16 pins used for switching regulator operation. For this switching regulator, we recommend keeping the output voltage at at least 2.85V volts. By using the 4.4V's maximal output voltage, adjusting voltage regulator can operate easily. With a maximum output voltage of 4.4V, DC DC switching regulator has a very high efficiency. This voltage regulator allows stable operation due to its high maximum operating temperature 85°C. Reliability is ensured at minimum DC DC switching regulator's operating temperatures of -40°C. With regard to the input voltage, it is compatible with a minimum voltage of 1.8V. 5V input voltage is supported at its maximum by this voltage regulator 12v.
