LT1941EFE#PBF Overview

There is an optimized performance in this voltage regulator because it utilizes the Tube package. There are 28 terminations in this harley voltage regulator. There is a SWITCHING REGULATOR type analog IC in this voltage regulator 12v that is used to convey analog signals. The space-saving 28-TSSOP (0.173, 4.40mm Width) Exposed Pad package is available for this voltage regulator. There are 3 outputs on DC DC switching regulator. On the output pins of this DC DC switching regulator, there is a Adjustable output generated. This voltage regulator 12v fits the Surface Mount mounting. The operating temperature should be kept at 0°C~70°C TA when the voltage regulator 12v is in operation. 1.1MHz is the switching frequency of this DC-DC switching regulator. Regulator 3.5V can operate with dc to dc voltage regulator's minimum input voltage 3.5V. The adjusting voltage regulator's output voltage (Min/Fixed) is 0.628V. Featuring a 1.5A Switch 2A Switch 3A Switch output current, dc to dc voltage regulator offers maximum design flexibility. There is a voltage regulator maximum input voltage of 25V. A regulator with this 260 peak reflow temperature is essentially indestructible. The voltage regulator 12v is designed to provide a nominal input voltage of 5V for operation. I would like to point out that this voltage regulator belongs to the Switching Regulator or Controllers subcategory. In the particular voltage regulators, the LT1941 family is represented. The adjusting voltage regulator's output voltage is maintain at 24V. During switching regulator operation, 28 pins are used. For this switching regulator, we recommend keeping the output voltage at at least 628mV volts. DC DC switching regulator is able to operate in an easy way on the basis of the maximal output voltage of 25V 40V Switch. There is a maximum output voltage of 40V from this voltage regulator 12v. A dc to dc voltage regulator's frequency of 1.35MHz is sufficient for maintaining high accuracy. It is a voltage regulator 12v that has a 1 channel configuration.
