L7987L Overview
optimized performance is achieved by utilizing the Tube package in this voltage regulator. A voltage regulator consists of 16 terminations. This regulator voltage is equipped with a type of analog integrated circuit that is called a SWITCHING REGULATOR voltage regulator. In order to save space, this harley voltage regulator is available in the 16-TSSOP (0.173, 4.40mm Width) Exposed Pad package. The voltage regulator is configured with 1 outputs. The adjusting voltage regulator generates Adjustable output. Switching regulators like this one can be mounted on the Surface Mount mounting system. Voltage regulators should be operated at -40°C~150°C TJ temperature while operating. The switching frequency of this DC-DC switching regulator reaches 250kHz~1.5MHz. According to the table below, DC DC switching regulator's output voltage (Min/Fixed) is equal to 0.8V. DC DC switching regulator's 2A output current allows for maximum design flexibility. An input voltage of 24V is required to meet the requirements of the switching regulator operation. In the particular voltage regulators, the L7987 family is represented. The adjusting voltage regulator's output voltage is maintain at 61V. In order for this switching regulator to work properly, the output voltage should be at least 800mVV. As a result, it is able to provide adjusting voltage regulator a maximum output voltage of 61V. An operating voltage of 4.5VV ensures adjusting voltage regulator reliable performance. The maximum supply voltage for the voltage regulator 12v is 61V, so DC DC switching regulator can operate with a maximum voltage of 61V.
