Working Principles
The ISL61853PCRZ operates as a linear voltage regulator. It regulates the output voltage by comparing the feedback voltage (FB) with a reference voltage. The enable pin (EN) controls the ON/OFF state of the regulator. When enabled, the IC adjusts the pass transistor to maintain the desired output voltage. If the output current exceeds the set limit, the overcurrent protection feature activates, protecting the connected devices. In case of excessive temperature, the thermal shutdown mechanism shuts down the regulator to prevent damage.
