MIC39151-2.5WT Application Field and Working Principle

The MIC39151-2.5WT is a low-dropout (LDO) linear voltage regulator offering a combination of output current (2.5A) and very low dropout voltage (100mV @2.5A). Created by Microchip Technology, Inc as part of a series of LDOs for gaming and audio applications, the MIC39151-2.5WT offers a wide range of features such as internal current and thermal overload protection, reverse current protection, fast transient response, and an adaptive-sensing topology that allows for an excellent line and load regulation. In addition, the MIC39151-2.5WT has an operating temperature range of -40 to 125^oC, a low quiescent current of 20µA, and a fast start-up time of only 500us.

As a linear voltage regulator, the MIC39151-2.5WT belongs to the PMIC (power management IC) family. It is specifically a voltage regulator in the Linear category, and it is created to provide specific output voltage and current levels needed in gaming and audio applications.

How the MIC39151-2.5WT Works

The MIC39151-2.5WT is a low-dropout linear voltage regulator, meaning that it provides regulated output voltage while allowing the input voltage to “drop-out” a minimal amount. The device uses an external N-channel enhancement mode MOSFET and a PMOS as its main switching element, which is designed to regulate the output voltage regardless of changes in both load and line conditions. This feature provides excellent line and load regulation.

The MIC39151-2.5WT is designed with low dropout (LDO) and adaptive sensing topology. This topology allows it to operate with only a tiny difference between input voltage and output voltage. In other words, the MIC39151-2.5WT can handle an input voltage that is slightly smaller than its output voltage, reducing power losses and improving the regulator’s efficiency. The device also has enable pin which allows the user to enable or disable the regulator by using a digital logic signal.

The MIC39151-2.5WT also has an internal current limit set at 2.5A, which helps protect the IC from short-circuit faults and protects the system from damage due to excessive current. The internal thermal overload protection circuitry also helps protect from thermal overload conditions. In addition, the MIC39151-2.5WT has an excellent transient response time of only 500us.

Application and Usage of the MIC39151-2.5WT

Due to its combination of features such as very low dropout voltage, robust protection, low quiescent current, and fast start-up time, the MIC39151-2.5WT is an ideal LDO voltage regulator for gaming and audio applications such as gaming consoles, amplifiers, audio systems, and multi-chip modules. Being part of a series of LDOs, the MIC39151-2.5WT also can be used in other sophisticated applications such as portable media players and VoIP, where it is desirable to have a more efficient power conversion and improved transient response.

Conclusion

The MIC39151-2.5WT is a low-dropout linear voltage regulator specifically designed to provide optimized voltage and current levels needed for gaming and audio applications. It uses an adaptive-sensing topology and a combination of internal protection mechanisms, providing excellent line and load regulation even with changes in both load and line conditions. The MIC39151-2.5WT is an ideal LDO voltage regulator for gaming and audio applications, as well as for applications with more sophisticated requirements.
