S-1333C35-A4T1U3 Working Principle

The S-1333C35-A4T1U3 is a linear voltage regulator which works based on the basic principles of resistive voltage division. When a higher voltage is supplied to its input terminal, the internal circuitry of the regulator divides this voltage into two parts. The lower part is the output voltage and the difference between its input and output is the dropout voltage.The output voltage is regulated by employing a servo-loop feedback mechanism. This servo-loop monitors the output voltage continuously, and if any change is detected, it triggers an internal circuitry which will adjust the input voltage accordingly, thus maintaining the output voltage at its desired level. The S-1333C35-A4T1U3 offers protection against a variety of faults such as overload, under-voltage, over-temperature and short circuit. The IC also has an active current-limit feature, which prevents any damage due to higher-than-expected current draw.
