L4977A Overview
optimized performance is achieved by utilizing the Tube package in this voltage regulator. Throughout this voltage regulator, there are 15 terminations. As a matter of fact, the type of analog IC that this voltage regulator 12v is equipped with is called SWITCHING REGULATOR. This harley voltage regulator is available in the Multiwatt-15 (Vertical, Bent and Staggered Leads) package for the purpose of space saving. There are 1 outputs configured on this voltage regulator 12v. The adjusting voltage regulator generates Adjustable output. Through Hole-mounting is compatible with this switching regulator. In order for it to operate properly, dc to dc voltage regulator's operating temperature should be at -40°C~150°C TJ. The switching frequency of this DC-DC switching regulator reaches 200kHz~500kHz. A dc to dc voltage regulator's minimum input voltage of 15V is required for this voltage regulator to operate. 50V volts is DC DC switching regulator's maximum input voltage. For operation, switching regulator requires a nominal input voltage of 35V. DC DC switching regulator is part of the Switching Regulator or Controllers subcategory and can be found in the Switching Regulator or Controllers category. As a member of the L4977 family of DC/DC regulators, this is a DC/DC regulator. A voltage of 40V volts can be produced by voltage regulator. In order to operate voltage regulator, 15 pins are required. There should be at least a 5.1V volt output voltage for this switching regulator in order to make it work properly. A 7A A maximum output current is required to meet the switching regulator operation requirements. A maximum voltage of 40V can be obtained from the regulator voltage. DC-DC switching regulator with supply voltage 50V.
