LT1931AIS5#TRMPBF Product Details
LT1931AIS5#TRMPBF Overview
optimized performance is achieved by utilizing the Tape & Reel (TR) package in this voltage regulator. This harley voltage regulator has 5 terminations. As a matter of fact, the type of analog IC that this voltage regulator 12v is equipped with is called SWITCHING REGULATOR. Due to DC DC switching regulator's space saving design, this voltage regulator is available in a SOT-23-5 Thin, TSOT-23-5 package. The voltage regulator is configured with 1 outputs. This DC DC switching regulator generates Adjustable output on its output pins. As the name implies, this voltage regulator 12v is designed for mounting on a Surface Mount bracket. When operating, adjusting voltage regulator's operating temperature should be kept at -40°C~85°C TA. A DC-DC switching regulator such as this one switches at 2.2MHz. A dc to dc voltage regulator's minimum input voltage of 2.45V is required for this voltage regulator to operate. It is evident from the table below that adjusting voltage regulator's output voltage (Min/Fixed) is equal to -1.255V. The output current of 1A makes dc to dc voltage regulator feature maximum design flexibility. Voltage regulator has a maximum input voltage of 16V. This voltage regulator's peak reflow temperature is so high as to make it virtually indestructible. To meet the switching regulator operation requirements, a nominal input voltage of 3V is provided. A voltage regulator 12v such as this falls under the Switching Regulator or Controllers category and belongs to this category. There is a DC/DC regulator in this family that belongs to the LT1931 family. The voltage DC DC switching regulator can provide is up to -34V volts. There are 5 pins that are used for the operation of the voltage regulator 12v. Ideally this switch regulator should have an output voltage of about -1.255V at the very least. The maximum output voltage of this regulator voltage is -34V.
