LT3957IUHE#PBF Product Details

LT3957IUHE#PBF Overview


optimized performance is achieved by utilizing the Tube package in this voltage regulator. There are 36 terminations in this voltage regulator. As a matter of fact, the type of analog IC that this voltage regulator 12v is equipped with is called SWITCHING REGULATOR. Space savings are achieved by placing this voltage regulator in the 36-WFQFN, 28 Leads, Exposed Pad package. There are 1 outputs on DC DC switching regulator. The adjusting voltage regulator generates Adjustable output. This switching regulator is designed to fit the Surface Mount mounting system. During switching regulator operation, the operating temperature should remain at -40°C~125°C TJ. A DC-DC switching regulator of this type operates at a switching frequency of 100kHz~1MHz. A dc to dc voltage regulator's minimum input voltage of 3V is required for this voltage regulator to operate. The output voltage (Min/Fixed) of this voltage regulator 12v is 1.6V. This voltage regulator 12v offers maximum design flexibility with an output current of 5A Switch. As a result of the 225 peak reflow temperature, this regulator is essentially indestructible. An input voltage of 24V is required to meet the requirements of the switching regulator operation. This voltage regulator is included in the Switching Regulator or Controllers subcategory. In this case, the DC/DC regulator belongs to the family LT3957. The voltage DC DC switching regulator can produce is 40V volts. The switching regulator operation of the system is controlled by 28 pins. The maximal output voltage of 40V Switch allows adjusting voltage regulator for simple operation. This harley voltage regulator is more efficient and stable due to its ALSO OPERATES AS LDO REGULATOR feature.
