Working Principle

The S-1133B32-U5T1G is based on a 3-terminal adjustment positive linear voltage regulator IC. It has a high-performance, low power consumption wide input voltage range and high frequency operation characteristics. The device is powered by a fixed input voltage (Vin), typically coming from a battery. The circuit then passes the fixed input voltage through an error amplifier and a reference voltage circuit. The comparison of the error signal voltage and the reference voltage signal is done by an internal voltage comparator.

The output voltage of the linear regulator is set by controlling the error amplifier feedback loop. The error amplifier adjusts the output voltage of the regulator by controlling the current through a pass element, typically a P-channel MOSFET. The current flow through the pass element varies until the output voltage of the error amplifier matches the reference voltage. When the two voltages match, the current output of the regulator is determined by the reference voltage of the regulator.

The S-1133B32-U5T1G also includes a current limit circuit, an over-temperature protection circuit and a thermal shutdown circuit. The output voltage and current of the regulator are monitored by an internal voltage and current comparator circuit. The thermal overload protection prevents the output voltage and current of the regulator from exceeding the value set by the temperature protection circuit.
