LT3508IUF#PBF Overview

A Tube package is used in this voltage regulator to optimize performance. There are 24 terminations in this voltage regulator. There are two types of analog ICs on this voltage regulator. The first type is a DUAL SWITCHING CONTROLLER-type IC. In order to save space, this voltage regulator is packaged in the 24-WFQFN Exposed Pad package. DC DC switching regulator is configured with 2 outputs. On the output pins of this DC DC switching regulator, there is a Adjustable output generated. As the name implies, this voltage regulator 12v is designed for mounting on a Surface Mount bracket. As long as its operating temperature is -40°C~125°C TJ, dc to dc voltage regulator should perform well. A DC-DC switching regulator of this type operates at a switching frequency of 920kHz~1.06MHz. The voltage regulator can operate with a dc to dc voltage regulator's minimum input voltage of 3.7V. As shown in the table below, adjusting voltage regulator's output voltage (Min/Fixed) is equal to 0.8V. The maximum input voltage of this voltage regulator 12v is 36V. 260 is essentially indestructible due to DC DC switching regulator's peak reflow temperature. The voltage regulator 12v is designed to provide a nominal input voltage of 12V for operation. The regulator voltage that you are looking at belongs to the subcategory Switching Regulator or Controllers. DC/DC regulators of this type are part of the LT3508 family of voltage regulator 12vs. A voltage of 35.28V volts can be produced by voltage regulator. In order to operate voltage regulator, 24 pins are required. For this switching regulator, it is recommended that the output voltage is at least 800mV volts. With a maximum output voltage of 35.28V, DC DC switching regulator has a very high efficiency. Voltage regulator consumes 320μA A of quiescent current without being affected by external factors.
