Working Principles

The XC6123C416MR-G is a voltage regulator that maintains a fixed output voltage regardless of input voltage fluctuations. It utilizes a feedback mechanism to compare the output voltage with a reference voltage and adjusts the internal circuitry accordingly. This feedback loop ensures a stable output voltage within the specified range.

When the enable pin (EN) is high, the regulator operates normally, regulating the input voltage (VIN) to the fixed output voltage (VOUT). Conversely, when the enable pin is low, the regulator enters a low-power mode, reducing its quiescent current and minimizing power consumption.
