LT3991EMSE-5#PBF Overview
For optimal performance, this voltage regulator uses the Tube package. In this voltage regulator, there are 10 terminations. A SWITCHING REGULATOR analog IC is used in this voltage regulator 12v, which is the type of analog IC that this voltage regulator 12v is equipped with. For space-saving purposes, this voltage regulator is available in the 10-TFSOP, 10-MSOP (0.118, 3.00mm Width) Exposed Pad package. 1 outputs of voltage regulator are configured. On the output pins of this DC DC switching regulator, there is a Fixed output generated. Surface Mount-mount switching regulator. -40°C~125°C TJ should be the operating temperature when voltage regulator is operating. This voltage regulator 12v reaches a switching frequency of 200kHz~2MHz. Voltage regulators like this one can operate at least with 4.3V as the dc to dc voltage regulator's minimum input voltage. There is a adjusting voltage regulator's voltage output (Min/Fixed) of 5V. DC DC switching regulator's 1.2A output current allows for maximum design flexibility. Voltage regulator's input voltage can reach 55V. The voltage regulator 12v is designed to provide a nominal input voltage of 12V for operation. This voltage regulator is included in the Switching Regulator or Controllers subcategory. DC/DC regulators such as this one belong to the LT3991 family of products. The adjusting voltage regulator's output voltage is maintain at 5V.
