LT1940LEFE#PBF Overview
A Tube package is used in this voltage regulator to optimize performance. In this voltage regulator, there are a total of 16 terminations. As a matter of fact, the type of analog IC that this voltage regulator 12v is equipped with is called DUAL SWITCHING CONTROLLER. In order to save space, this voltage regulator is packaged in the 16-TSSOP (0.173, 4.40mm Width) Exposed Pad package. There are 2 outputs configured on this voltage regulator 12v. DC DC switching regulators like this one generate Adjustable outputs on their output pins to handle the power management. Surface Mount-mount switching regulator. Operating at -40°C~85°C TA is the recommended temperature for adjusting voltage regulator's operation. A DC-DC switching regulator such as this one switches at 1.1MHz. Voltage regulators like this one can operate at least with 3.6V as the dc to dc voltage regulator's minimum input voltage. There is a adjusting voltage regulator's voltage output (Min/Fixed) of 1.25V. Voltage regulators' input voltage is limited to 7V. As a result of the 260 peak reflow temperature, this regulator is essentially indestructible. For operation, switching regulator requires a nominal input voltage of 5V. The regulator voltage that you are looking at belongs to the subcategory Switching Regulator or Controllers. DC/DC regulators such as this one belong to the LT1940 family of products. The voltage DC DC switching regulator can produce is 6.3V volts. To operate the voltage regulator 12v, 16 pins are required. For this switching regulator, we recommend keeping the output voltage at at least 1.25V volts. For switching regulator maximum operation, dc to dc voltage regulator delivers 1.4A A. A maximum voltage of 6.16V can be obtained from the regulator voltage. With a frequency of 1.1GHz, dc to dc voltage regulator has high accuracy.
