Working Principles

The ZXCL260E5 is a linear voltage regulator that uses a pass transistor to regulate the output voltage. It operates by comparing the feedback voltage (FB pin) with a reference voltage, adjusting the pass transistor's resistance to maintain a stable output voltage. The enable pin (EN) controls the device's operation, allowing it to enter low-power modes when not needed.
