Products Detail

L4973D3.3 Overview

Using the Tube package, this voltage regulator optimizes the performance of the voltage regulator 12v. A voltage regulator consists of 20 terminations. There is a SWITCHING REGULATOR type analog IC in this voltage regulator 12v that is used to convey analog signals. There is a 20-SOIC (0.295, 7.50mm Width) package available for this voltage regulator, as DC DC switching regulator is space-saving. 1 outputs have been configured in the voltage regulator 12v. On its output pins, this adjusting voltage regulator generates Adjustable (Fixed) output. Switching regulators like this one can be mounted on the Surface Mount mounting system. In order for it to operate properly, dc to dc voltage regulator's operating temperature should be at -40°C~150°C TJ. In this voltage regulator 12v, the switching frequency is 100kHz~300kHz. There is a adjusting voltage regulator's voltage output (Min/Fixed) of 0.5V 3.3V. A regulator with this 250 peak reflow temperature is essentially indestructible. For operation, switching regulator requires a nominal input voltage of 24V. There is a subcategory of this regulator voltage called Switching Regulator or Controllers. L4973 is a family of voltage regulators that belong to the DC/DC industry. Voltage regulator is capable of giving voltage at 50V volts. In order to operate voltage regulator, 20 pins are required. This voltage regulator 12v should be configured with an output voltage that is at least 500mV. For switching regulator maximum operation, dc to dc voltage regulator delivers 3.5A A. The maximal output voltage of 50V allows DC DC switching regulator to be operated easily. Using this voltage regulator 12v, you will be able to get the maximum output voltage of 50V. With a supply voltage of 55V, this harley voltage regulator works. The dc to dc voltage regulator's minimum supply voltage of 8V volts ensures reliable performance.
