LT3990EMSE#PBF Overview
For optimal performance, this voltage regulator uses the Tube package. There are 16 terminations in this voltage regulator. This regulator voltage is equipped with a type of analog integrated circuit that is called a SWITCHING REGULATOR voltage regulator. For space-saving purposes, this voltage regulator is available in the 16-TFSOP (0.118, 3.00mm Width) Exposed Pad package. The voltage regulator 12v has 1 outputs. There are output pins on this DC DC switching regulator that generate Adjustable output. Switching regulators like this one can be mounted on the Surface Mount mounting system. Keeping dc to dc voltage regulator's operating temperature at -40°C~125°C TJ is essential when operating. A DC-DC switching regulator such as this one switches at 210kHz~2.3MHz. There is no dc to dc voltage regulator's minimum input voltage requirement for this regulator. DC DC switching regulator's output voltage (Min/Fixed) amounts to 1.21V. A maximum design flexibility is provided by the 350mA output current of voltage regulator. There is a maximum input voltage of 62V for this voltage regulator 12v. Its 260 peak reflow temperature makes this regulator essentially indestructible. To meet the switching regulator operation requirements, a nominal input voltage of 12V is provided. The regulator voltage is included in the Switching Regulator or Controllers subcategory of voltage regulators. As a member of the LT3990 family of DC/DC regulators, this is a DC/DC regulator. There is a possibility that DC DC switching regulator can give voltage at 3.3V volts. 25V's maximal output voltage allows adjusting voltage regulator to operate easily.
