A4447SLJTR-T Overview


optimized performance is achieved by utilizing the Tape & Reel (TR) package in this voltage regulator. There are 8 terminations in this harley voltage regulator. There is a SWITCHING REGULATOR type analog IC in this voltage regulator 12v that is used to convey analog signals. In order to save space, this voltage regulator is packaged in the 8-SOIC (0.154, 3.90mm Width) Exposed Pad package. In this case, DC DC switching regulator has 1 outputs configured to it. As you can see, this DC DC switching regulator generates Adjustable output on its output pins. Surface Mount-mounting is compatible with this switching regulator. Voltage regulators should be operated at -20°C~85°C TA temperature while operating. The output voltage of this voltage regulator (Min/Fixed) amounts to 0.8V volts. This voltage regulator's peak reflow temperature is so high as to make it virtually indestructible. As a result of DC DC switching regulator's design, it is designed to provide an input voltage of 42V for the purposes of operation. In terms of category, this voltage regulator 12v falls into the Switching Regulator or Controllers category. There is a DC/DC regulator in this family that belongs to the A4447 family. Voltage can be produced at 24V volts by voltage regulator. In order to operate voltage regulator, 8 pins are required. For this switching regulator, it is recommended that the output voltage is at least 800mV volts. A maximum output current of 2A A is provided to meet the switching regulator operation requirements. By using 24V as the maximum output voltage, adjusting voltage regulator is easy to operate. There is a maximum output voltage of 24V from this voltage regulator 12v. The dc to dc voltage regulator's minimum supply voltage of 8V volts ensures reliable performance. It is able to operate from a maximum supply voltage of 50V, which is suitable for DC DC switching regulator's operation.
