L4978 Overview


It is designed to provide optimal performance by utilizing the Tube package. Throughout this voltage regulator, there are 8 terminations. 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 harley voltage regulator is available in the 8-DIP (0.300, 7.62mm) package. DC DC switching regulator is configured with 1 outputs. Adjustable outputs are generated on the output pins of this adjusting voltage regulator. Through Hole-mounting is compatible with this switching regulator. When operating, adjusting voltage regulator's operating temperature should be kept at -40°C~150°C TJ. A DC-DC switching regulator of this type operates at a switching frequency of 100kHz~300kHz. The voltage regulator can operate with a dc to dc voltage regulator's minimum input voltage of 8V. Voltage regulators' input voltage is limited to 55V. To meet the switching regulator operation requirements, a nominal input voltage of 24V is provided. Listed under the subcategory of Switching Regulator or Controllers is this voltage regulator 12v. In the particular voltage regulators, the L4978 family is represented. Voltage of voltage regulator can be delivered at 50V volts. To operate the voltage regulator 12v, 8 pins are required. Ideally this switch regulator should have an output voltage of about 3.3V at the very least. Accordingly, dc to dc voltage regulator's maximum output current is 2A A. The maximum voltage of voltage regulator 12v DC DC switching regulator can produce is 50V, which is the highest available. With 55V as the supply voltage, this DC-DC switching regulator will operate. It is capable of maintaining high accuracy with the dc to dc voltage regulator's frequency of 300kHz.
