Working Principles

The NCP301LSN11T1G operates by comparing the input voltage with the threshold voltage set by external resistors. If the input voltage drops below the threshold voltage, the reset output is activated, indicating a low-voltage condition. This allows connected circuits to respond accordingly and prevent any potential damage or malfunction.
