LT3957EUHE#PBF Overview


For optimal performance, this voltage regulator uses the Tube package. As you can see, this harley voltage regulator contains 36 terminations. As a matter of fact, the type of analog IC that this voltage regulator 12v is equipped with is called SWITCHING REGULATOR. The space-saving 36-WFQFN, 28 Leads, Exposed Pad package is available for this voltage regulator. There are 1 outputs configured on the voltage regulator. ICs such as this voltage regulator are capable of generating Adjustable outputs through their output pins. Switching regulators like this one can be mounted on the Surface Mount mounting system. As long as its operating temperature is -40°C~125°C TJ, dc to dc voltage regulator should perform well. The switching frequency of this DC-DC switching regulator reaches 100kHz~1MHz. Regulator 3V can operate with dc to dc voltage regulator's minimum input voltage 3V. According to the table below, DC DC switching regulator's output voltage (Min/Fixed) is equal to 1.6V. DC DC switching regulator's maximum design flexibility comes from its output current of 5A Switch. As a result of its peak reflow temperature, this voltage regulator is virtually indestructible. 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. DC/DC regulators of this type are part of the LT3957 family of voltage regulator 12vs. Voltage regulator is capable of giving voltage at 40V volts. During switching regulator operation, 28 pins are used. Voltage regulator's maximal output current reaches 5A A to meet the operation requirements. The maximum output voltage of 40V Switch makes DC DC switching regulator easy to operate. DC DC switching regulator offers a maximum output voltage of 40V as its maximum output voltage. Switching regulators with the ALSO OPERATES AS LDO REGULATOR feature are more efficient and stable.
