L4971 Overview
For optimal performance, this voltage regulator uses the Tube package. There are 8 terminations in this voltage regulator. There are two types of analog ICs on this voltage regulator. The first type is a SWITCHING REGULATOR-type IC. The harley voltage regulator is available as a 8-DIP (0.300, 7.62mm) package to save space. The voltage regulator is configured with 1 outputs. This DC DC switching regulator generates Adjustable output on its output pins. Switching regulators like this one can be mounted on the Through Hole mounting system. As long as its operating temperature is -40°C~150°C TJ, dc to dc voltage regulator should perform well. DC-DC switching regulators reach 100kHz~300kHz switching frequencies. There is no dc to dc voltage regulator's minimum input voltage requirement for this regulator. The maximum input voltage of voltage regulator is 55V. For operation, switching regulator requires a nominal input voltage of 24V. There is a subcategory called Switching Regulator or Controllers that includes this voltage regulator. As part of the L4971 series of regulators, the voltage regulators can be found. The adjusting voltage regulator's output voltage is maintain at 50V. The switching regulator operation is carried out by 8 pins. The output voltage of this voltage regulator 12v should at least be set at 3.3V volts at all times. For switching regulator maximum operation, dc to dc voltage regulator delivers 1.5A A. By using 50V as the maximum output voltage, adjusting voltage regulator is easy to operate. With a maximum output voltage of 50V, DC DC switching regulator has a very high efficiency.
