LT3991EMSE#PBF Overview


A Tube package is used in this voltage regulator to optimize performance. A voltage regulator consists of 10 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. Space-saving 10-TFSOP, 10-MSOP (0.118, 3.00mm Width) Exposed Pad packages are available for this harley voltage regulator. The voltage regulator 12v has 1 outputs. As you can see, this DC DC switching regulator generates Adjustable output on its output pins. A Surface Mount mounting is required for this switching regulator. As long as its operating temperature is -40°C~125°C TJ, dc to dc voltage regulator should perform well. DC-DC switching regulators reach 200kHz~2MHz switching frequencies. The regulator is capable of operating with a dc to dc voltage regulator's minimum input voltage of 4.3V. It is evident from the table below that adjusting voltage regulator's output voltage (Min/Fixed) is equal to 1.19V. The output current of 1.2A makes dc to dc voltage regulator feature maximum design flexibility. Voltage regulator has a maximum input voltage of 55V. 260 is essentially indestructible due to DC DC switching regulator's peak reflow temperature. The voltage regulator 12v is designed to provide a nominal input voltage of 12V for operation. I would like to point out that this voltage regulator belongs to the Switching Regulator or Controllers subcategory. As a member of the LT3991 family of DC/DC regulators, this is a DC/DC regulator. The adjusting voltage regulator's output voltage is maintain at 3.3V. By using the 30V's maximal output voltage, adjusting voltage regulator can operate easily.
