Working Principles

The ISL9012IRNJZ-T operates as a low dropout voltage regulator by comparing the feedback voltage (FB) with a reference voltage. It adjusts the pass transistor's resistance to maintain a stable output voltage, compensating for changes in load and input voltage.

When the enable pin (EN) is high, the regulator is active, and the output voltage is regulated according to the feedback voltage. When the enable pin is low, the regulator enters a low-power state, reducing quiescent current and conserving energy.
