Working Principle

The NCP729FC26T2G linear regulator uses a resistive feedback loop to control the output voltage. It uses an external resistor divider to divide the output voltage and then compares it to the reference voltage. The output voltage is then adjusted by adjusting the current flowing through the internal pass device (MOSFET).When the supply voltage and output voltage are equal, the output transistor is turned off and no current flows through the pass element. Since the output voltage is determined by the ratio of the two resistors, the output voltage can be set at any level within the device\'s operating voltage range.When the output voltage drops below the desired voltage, the output transistor turns on, allowing the current to flow through the pass element and maintain the output voltage at the desired level. In this way, the output voltage is controlled and adjusted to the desired level.

Conclusion

The NCP729FC26T2G is a high-efficiency, wide-input voltage linear regulator from ON Semiconductor. This device offers low dropout voltage, fast transient response, and low quiescent current, making it ideal for application fields such as high efficiency switched-mode power supply solutions, smart home appliances, and power-sensitive system power management.
