S-1335G14-A4T2U3 is a linear voltage regulator IC which belongs to the PMIC – Voltage Regulators – Linear category. It mainly consists of the following components:

1. An integrated voltage comparator with adjustable current limiting threshold and latch function;

2. An operational amplifier with a wide range of input and output ranges;

3. A P-Channel MOSFET for controlling the output voltage;

4. A low voltage comparator with hysteresis for resetting the internal latch;

5. An adjustable internal voltage reference;

6. An adjustable current source for providing a proportional voltage drop across the output voltage.

The overall function of S-1335G14-A4T2U3 is to convert a fixed input voltage into a regulated output voltage. The voltage regulator IC can also be used to provide a variable regulated voltage depending on the input voltage and the setting of the reference voltage and current limit. The IC is suitable for use in applications where excessive current must be prevented and where the output voltage needs to be regulated over a wide range of input voltages.

The IC has an adjustable internal voltage reference which can be used to set the maximum output voltage of the device. The integrated voltage comparator monitors the voltage across the output voltage, and when the voltage across the output voltage exceed the selected voltage reference, the voltage comparator activates the reset latch. This reset latch then disconnects the output voltage from the power supply and prevents excessive current from flowing through the output voltage. The output voltage is then regulated to the selected reference voltage.

The current limit comparator of the IC monitors the current flowing through the output voltage, and when the current flows reaches the selected limit, the voltage comparator captures the second latch, which then activates the P-Channel MOSFET, thus controlling the output voltage. This reduces the output voltage and prevents any further increase in current.

The S-1335G14-A4T2U3 is suitable for use in many applications including Intel Haswell-based ultrabooks, embedded microcontroller and programming hardware, embedded DC/DC converters, automotive systems, military and avionics systems, and many other applications where a regulated voltage is required.

The IC has an integrated thermal shutdown feature which activates in the event of an over temperature condition. This helps to protect the device from damage. It also has a built-in fast response over-voltage protection which disconnects the output from the power supply in the case of an over-voltage condition.

In conclusion, the S-1335G14-A4T2U3 is a linear voltage regulator IC which belongs to the PMIC – Voltage Regulators – Linear category. It is suitable for many applications where a regulated voltage is required, and provides protection from excessive current, over-voltage, and over-temperature conditions.
