LT3991IDD#PBF Overview
It uses the Tube package in order to optimize the performance of this voltage regulator. Throughout this voltage regulator, there are 10 terminations. 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. The voltage regulator is configured with 1 outputs. There are output pins on this DC DC switching regulator that generate Adjustable output. This switching regulator is designed to fit the Surface Mount mounting system. Voltage regulators should be operated at -40°C~125°C TJ temperature while operating. In this voltage regulator 12v, the switching frequency is 200kHz~2MHz. The voltage regulator can operate with a dc to dc voltage regulator's minimum input voltage of 4.3V. There is a adjusting voltage regulator's voltage output (Min/Fixed) of 1.19V. DC DC switching regulator's 1.2A output current allows for maximum design flexibility. Voltage regulator has an input voltage (Max) of 55V. A regulator voltage's peak reflow temperature amounts to 260 being indestructible. An input voltage of 12V is required to meet the requirements of the switching regulator operation. In terms of category, this voltage regulator 12v falls into the Switching Regulator or Controllers category. DC/DC regulators of this type are part of the LT3991 family of voltage regulator 12vs. A voltage of 3.3V volts can be produced by voltage regulator. On the basis of the maximum output voltage of 30V, adjusting voltage regulator can be operated easily.
