NCP718BSNADJT1G

Working Principle

This linear voltage regulator operates according to the classical linear regulator circuit, where a difference in voltage, between the input voltage and the output voltage, is defined and maintained by an external feedback loop, sawtooth and immittance. The output voltage is controlled by an internal filter resistors, capacitor, FET and Voltage Regulator Unit (VRU). The current through the VRU is controlled by the sawtooth responsive circuit, while the FET ensures that the current remains constant. The immittance provide additional impedance which limits the output current in the event of a short circuit.

The linear voltage regulator also works with a thermal compensation mechanism. The voltage regulator has an integrated circuit thermal diode, which helps to prevent damage and ensures the device remains at optimal working temperature under extreme conditions. The thermistor monitors the temperature of the device and changes the output voltage accordingly, to prevent it from getting too hot.

The NCP718BSNADJT1G is a low-cost and efficient voltage regulator that can be integrated into a variety of applications with ease. It is an ideal choice for those seeking a reliable, precision and highly efficient regulator with low power consumption.
