LT1945EMS#PBF Overview

For optimal performance, this voltage regulator uses the Tube package. There are 10 terminations in this voltage regulator. There are two types of analog ICs in this voltage regulator 12v: DUAL SWITCHING CONTROLLER ICs, which are the ones used in older voltage regulator 12vs. The space-saving 10-TFSOP, 10-MSOP (0.118, 3.00mm Width) package is available for this voltage regulator. There are 2 outputs on DC DC switching regulator. Adjustable outputs are generated on the output pins of this adjusting voltage regulator. There is a switching regulator that is compatible with the Surface Mount mounting. The operating temperature should be kept at 0°C~70°C TJ when the voltage regulator 12v is in operation. Input voltage 1.2V is the dc to dc voltage regulator's minimum input voltage required for operation of the voltage regulators. DC DC switching regulator's output voltage (Min/Fixed) amounts to ±1.23V. The output current of 250mA Switch makes dc to dc voltage regulator feature maximum design flexibility. Voltage regulator has an input voltage (Max) of 15V. Its 260 peak reflow temperature makes this regulator essentially indestructible. An input voltage of 1.2V is required for switching regulator operation. I would like to point out that this voltage regulator belongs to the Switching Regulator or Controllers subcategory. DC/DC regulators such as this one belong to the LT1945 family of products. By using the ±34V's maximal output voltage, adjusting voltage regulator can operate easily.
