Introduction to S-8351A27MC-J2MT2U

The S-8351A27MC-J2MT2U is a linear voltage regulator integrated circuit (IC) designed and developed by ROHM Semiconductor. It is classified as a PMIC (power management integrated circuit) Voltage Regulator, and included in the DC-DC Switching Regulator category.

Application Field of S8351A27MC-J2MT2U

The S8351A27MC-J2MT2U is designed to regulate the output voltage of a power source to the desired level. It is mostly used in automotive and industrial applications where the required voltage level must be kept stable and unaffected by voltage fluctuations. The S-8351A27MC-J2MT2U is a highly efficient power regulating device that is capable of regulating a wide input voltage range and is able to supply a steady output regardless of changes in the input voltage and load.

Features of S8351A27MC-J2MT2U

The S-8351A27MC-J2MT2U is designed to operate with a minimum voltage of 3.3V and a maximum voltage of 36V. It is capable of supplying up to 2A of output current and can control the output voltage accurately over a range of 0.6V to 5.5V. To protect the power sources, this device is also equipped with over-voltage protection, over-temperature protection, current protection, and reverse-current protection.

Working Principle of S8351A27MC-J2MT2U

The S8351A27MC-J2MT2U is a buck regulator, meaning it can reduce the input voltage by converting current from a higher voltage source to a lower voltage. This voltage regulator is designed to take unregulated input voltage and reduce it to a precise and steady output voltage.The S8351A27MC-J2MT2U operates by building a conducting path between the input voltage and an output capacitor. This is done by a series of transistors activated by the control IC embedded within the IC. The control IC is responsible for monitoring the voltages and current, and controlling the transistors to ensure the desired output voltage is achieved.When the control IC detects that the output voltage has gone higher than the required value, it reduces the conducting path and lowers the current from the input. Similarly, if the output voltage is lower than required, it will extend the conducting path and increase the current from the input. In this way, the output voltage is precisely maintained at the set level.

Conclusion

The S-8351A27MC-J2MT2U voltage regulator is a versatile and efficient IC for automotive and industrial applications. It is capable of regulating a wide input voltage range and is able to precisely maintain the output voltage over a wide range of 0.6V to 5.5V. The S-8351A27MC-J2MT2U is also equipped with over-voltage protection, over-temperature protection, current protection, and reverse-current protection, making it a reliable and robust power regulating device.
