LM3668SD-4550/NOPB Overview
For optimal performance, this voltage regulator uses the Tape & Reel (TR) package. This harley voltage regulator has 12 terminations. A DUAL SWITCHING CONTROLLER type of analog IC is equipped with this regulator voltage, which is the type of analog IC that is used in it. For space-saving purposes, this voltage regulator is available in the 12-WFDFN Exposed Pad package. A total of 1 outputs are configured in this voltage regulator. DC DC switching regulators like this one generate Programmable outputs on their output pins to handle the power management. A voltage regulator 12v such as this one fits the Surface Mount mounting bracket. -40°C~85°C TA should be the operating temperature when voltage regulator is operating. DC-DC switching regulators reach 2.2MHz switching frequencies. There is a adjusting voltage regulator's voltage output (Min/Fixed) of 4.5V 5V. Its 260 peak reflow temperature makes this regulator essentially indestructible. An input voltage of 3.6V is required for switching regulator operation. The regulator voltage is included in the Switching Regulator or Controllers subcategory of voltage regulators. As part of the LM3668 series of regulators, the voltage regulators can be found. The voltage DC DC switching regulator can produce is 5V volts. In order to operate voltage regulator, 12 pins are required. This voltage regulator 12v should be configured with an output voltage that is at least 4.5V. A 1A A maximum output current is required to meet the switching regulator operation requirements. It provides the adjusting voltage regulator's maximal output voltage of 5V. This DC-DC switching regulator operates from a supply voltage of 5.5V. Voltage regulator consumes 45μA A of quiescent current without being affected by external factors. In this case, a dc to dc voltage regulator's minimum supply voltage of 2.5V volts is required to ensure reliable performance.
