LT3971IDD#TRPBF Product Details
LT3971IDD#TRPBF Overview
For optimal performance, this voltage regulator uses the Tape & Reel (TR) package. There are 10 terminations in this voltage regulator. There is a SWITCHING REGULATOR type analog IC in this voltage regulator 12v that is used to convey analog signals. In order to save space, this voltage regulator is packaged in the 10-WFDFN Exposed Pad package. There are 1 outputs configured on this voltage regulator 12v. Adjustable outputs are generated on the output pins of this adjusting voltage regulator. A Surface Mount mounting is required for this switching regulator. When operating, adjusting voltage regulator's operating temperature should be kept at -40°C~125°C TJ. 200kHz~2MHz is the switching frequency of this DC-DC switching regulator. This voltage regulator is able to operate with the minimal input voltage of 4.3V. The output voltage of this voltage regulator (Min/Fixed) amounts to 1.19V volts. A maximum design flexibility is provided by the 1.2A output current of voltage regulator. The maximum input voltage of this voltage regulator 12v is 38V. This voltage regulator's peak reflow temperature is so high as to make it virtually indestructible. To meet the operation requirements, voltage regulator is designed to provide 12V as the nominal input voltage. I would like to point out that this voltage regulator belongs to the Switching Regulator or Controllers subcategory. In this case, the DC/DC regulator belongs to the family LT3971. DC DC switching regulator is able to operate in an easy way on the basis of the maximal output voltage of 30V.
