L4974A Overview


For optimal performance, this voltage regulator makes use of the Tube package. In this voltage regulator, there are a total of 20 terminations. There are two types of analog ICs in this voltage regulator 12v: SWITCHING REGULATOR ICs, which are the ones used in older voltage regulator 12vs. The harley voltage regulator is available as a 20-DIP (0.300, 7.62mm) package to save space. A total of 1 outputs are configured in this voltage regulator. This DC DC switching regulator generates Adjustable output on its output pins. A voltage regulator 12v such as this one fits the Through Hole mounting bracket. The operating temperature should be kept at -40°C~150°C TJ when the voltage regulator 12v is in operation. In this voltage regulator 12v, the switching frequency is 100kHz~200kHz. A dc to dc voltage regulator's minimum input voltage of 15V is required for this voltage regulator to operate. The voltage regulator 12v is designed to provide a nominal input voltage of 35V for operation. I would like to point out that this voltage regulator belongs to the Switching Regulator or Controllers subcategory. There is a DC/DC regulator in this family that belongs to the L4974 family. At 40V volts, voltage regulator can provide voltage. There are 20 pins that are used for the operation of the voltage regulator 12v. In order to use this voltage regulator 12v at its full potential, the output voltage should be kept at at least 5.1V. The maximum output current reaches 3.5A A to meet the switching regulator operation requirements. By using the 40V's maximal output voltage, adjusting voltage regulator can operate easily. DC DC switching regulator offers a maximum output voltage of 40V as its maximum output voltage. With 50V as the supply voltage, this DC-DC switching regulator will operate. When the frequency is 200kHz, DC DC switching regulator can maintain high accuracy.
