L4970A Overview
For optimal performance, this voltage regulator makes use of the Tube package. A voltage regulator consists of 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. The voltage regulator 12v has 1 outputs. The adjusting voltage regulator generates Adjustable output. A Through Hole mounting is required for this switching regulator. Keeping dc to dc voltage regulator's operating temperature at -40°C~150°C TJ is essential when operating. In this voltage regulator 12v, the switching frequency is 200kHz. The regulator is capable of operating with a dc to dc voltage regulator's minimum input voltage of 15V. Voltage regulator is designed to provide a nominal input voltage of 35V to meet the operation requirements. I would like to point out that this voltage regulator belongs to the Switching Regulator or Controllers subcategory. In the particular voltage regulators, the L4970 family is represented. Voltage can be produced at 40V volts by voltage regulator. In order to operate voltage regulator, there are 15 pins that must be connected. Ideally this switch regulator should have an output voltage of about 5.1V at the very least. In order to meet the requirements of the switching regulator operation, the maximum output current reaches 10A A. By using 40V as the maximum output voltage, adjusting voltage regulator is easy to operate. The maximum output voltage of this regulator voltage is 40V. DC-DC switching regulator with 50V supply voltage. A dc to dc voltage regulator's frequency of 500kHz is sufficient for maintaining high accuracy.
