Application Fields

The MIC2215-NNNYML is ideally suited for a variety of applications, from general purpose to high power industrial use. First, the MIC2215-NNNYML is an excellent option for portable applications, due to its low quiescent current and low noise operation. It can be used as a power source in portable electronics, such as laptops, cellular phones and medical equipment. Additionally, the MIC2215-NNNYML can be used for portable battery charging applications, due to its capability to provide accurate voltage regulation for different levels of power requirements. Second, the MIC2215-NNNYML is suitable for a wide range of industrial applications. It can be used in power supply design, such as lightning systems and vehicle systems, as well as in applications that require high current output and very low noise operation. Additionally, the MIC2215-NNNYML can be used as a replacement for some types of linear voltage regulator chips, offering a more robust and reliable voltage regulator solution. Finally, the MIC2215-NNNYML is also suitable for a wide range of consumer applications. It can be used in audio systems, televisions, and even in recreational equipment, such as hand held game consoles.

Working Principle

The MIC2215-NNNYML is a Linear Voltage Regulator which uses a precision shunt regulator and two comparators for power supply design. The shunt regulator offers adjustable, fast response and error amplifier, while the two comparators ensure a precise voltage regulation regardless of load current and ambient temperature. When the input voltage is applied to the MIC2215-NNNYML, the shunt regulator and comparators check the input voltage. If the input voltage is higher than the targeted output voltage, the comparators reduce the output current and cause downward regulation. On the other hand, if the input voltage is less than the targeted output voltage, the comparators increase the output current and cause upward regulation. The adjustment of the output voltage can be done using an external voltage spreader circuit, providing an output voltage that is tightly regulated and independent from the input and load variations. In addition, the MIC2215-NNNYML has an over-temperature protection circuit which will limit the output current when it exceeds a predetermined temperature, thus protecting the device against thermal damage and allowing longer lifetime.

Conclusion

The MIC2215-NNNYML is a Linear Voltage Regulator that provides a wide adjustable output voltage range, low quiescent current and low noise operation. It is suitable for a wide range of applications, from general purpose to high power industrial use. The MIC2215-NNNYML includes a precision shunt regulator and two comparators for the power supply design, and its adjustable output voltage can be set using an external voltage reference spreader circuit, providing a tightly regulated output voltage regardless of input voltage and load variations. The MIC2215-NNNYML also contains an over-temperature protection circuit which will limit the output current when it exceeds a predetermined temperature.
