L4971D Overview
optimized performance is achieved by utilizing the Tube package in this voltage regulator. In this voltage regulator, there are 16 terminations. A SWITCHING REGULATOR type of analog IC is equipped with this regulator voltage, which is the type of analog IC that is used in it. Due to DC DC switching regulator's space saving design, this voltage regulator is available in a 16-SOIC (0.295, 7.50mm Width) package. In this case, DC DC switching regulator has 1 outputs configured to it. DC DC switching regulators like this one generate Adjustable outputs on their output pins to handle the power management. Surface Mount-mounting is compatible with this switching regulator. -40°C~150°C TJ should be the operating temperature when voltage regulator is operating. There is a switching frequency of 100kHz~300kHz for this voltage regulator 12v. Despite its low input voltage, this voltage regulator can operate. Voltage regulator has a maximum input voltage of 55V. 260 is essentially indestructible due to DC DC switching regulator's peak reflow temperature. For operation, voltage regulator provides a nominal input voltage of 24V. Listed under the subcategory of Switching Regulator or Controllers is this voltage regulator 12v. The L4971 family of DC/DC regulators includes this DC/DC regulator. Voltage of voltage regulator can be delivered at 50V volts. The switching regulator operation of the system is controlled by 16 pins. The output voltage for this switching regulator should be kept at 3.3V at least. Voltage regulator's maximal output current reaches 1.5A A to meet the operation requirements. 50V's maximal output voltage allows adjusting voltage regulator to operate easily. There is a maximum output voltage of 50V from this voltage regulator 12v. DC DC switching regulator's high accuracy can be maintained with a frequency of 300GHz.
