PMIC voltage regulators are one of the essential items needed to power and manage electrical components. The most common voltage regulator is the linear regulator. MIC5317-1.0YM5-T5 is a type of linear voltage regulator that can help device designers efficiently and reliably regulate power to the most stringent requirements. By understanding the application fields and working principles of this particular voltage regulator, users can choose the best device for their specification, design and application needs.

Application Fields

MIC5317-1.0YM5-T5 is an ultra-low, low-dropout (LDO) linear voltage regulator. It can provide up to 800mA of output current, and its output voltage range is from 2.4V to 8.4V. This feature make it suitable for a variety of applications that need any one of these voltages, such as automotive electronics, communications, networking, consumer electronics and audio applications. The low dropout voltage means that the MIC5317-1.0YM5-T5 can operate on a voltage rail as low as 1.25V, helping designers to save precious board space. This voltage regulator is also equipped with over-temperature, current monitor and thermal shutdown protection, so that it can be used in applications where a high level of system performance is needed.

Working Principle

As a Linear Voltage Regulator, the MIC5317-1.0YM5-T5 works on the basis of a resistive element. When power is applied, the voltage is regulated to the output terminal. The regulator provides a stable output voltage by decreasing or increasing the current through a resistive element. For current to flow, the input voltage must exceed the output voltage by a certain amount. This amount is called the dropout voltage. As the voltage increases, the resistor’s resistance decreases and the current flow increases. The output voltage is determined by the resistance of the regulator, its output current, and the value of the resistive element. The MIC5317-1.0YM5-T5 also provides a low-consumption shutdown mode which allows system power to be shut down while still retaining the original settings. Since it is an ultra low-dropout regulator, it can operate on a voltage rail as low as 1.25V, helping designers to save precious board space.

Conclusion

The MIC5317-1.0YM5-T5 is a versatile low-dropout linear voltage regulator. It can provide up to 800mA of output current, and its output voltage range spans from 2.4V to 8.4V. This wide range of voltages makes it ideal for many applications in the automotive, communications, networking, consumer and audio industries. The device is also equipped with over-temperature, current monitor and thermal shutdown protection, so it can be used in applications where a high level of system performance is needed. By understanding the application fields and working principles of this particular voltage regulator, users can choose the best device for their specification, design and application needs.
