The MIC2211-NNBML-TR is a voltage regulator that features low-dropout linear regulation. It is a high-side variable voltage regulator that offers excellent power supply regulation with fast transient response characteristics, making it ideal for a wide range of power supply applications. It is capable of switching up to 2A of current and can be used to regulate 3.3V, 5V, 6V, 8V, and 9V outputs.

The MIC2211-NNBML-TR is a three terminal voltage regulator and includes a control pin (isense) and an enable pin (enable). The control pin is connected to ground to control the output voltage. When a voltage above 2.85V is applied to the control pin, the output voltage is set to 4.7V. When a voltage below 2.85V is applied to the control pin, the output voltage is set to 0V. The enable pin is used to enable or disable the IC. When the IC is enabled, the output voltage is set to 4.7V. When disabled, the output voltage is set to 0V.

The MIC2211-NNBML-TR voltage regulator integrates current shunting and current limiting, which together provide excellent system stability and control. It also features modest quiescent current, making it ideal for low-power applications requiring low quiescent currents. It can operate from input voltage ranges of 3.0V to 10V, and has an adjustable output voltage range of 0.8V to 8V.

This voltage regulator is widely used in a variety of low-power applications such as microcontrollers, ASICs, sensors and other circuits requiring precise current regulation. It is suitable for space-limited, low-power applications. For example, it can be used in motherboards, peripheral cards, embedded systems, and system-on-a-chip designs. It is also suitable for battery operated systems, as it is designed for low quiescent current.

In addition, the MIC2211-NNBML-TR is capable of providing up to 2A of output current. This current can be sourced or sunk, and is limited to the rated value by a combination of current shunting and sensing resistors. The current is monitored to provide output current protection and thermal protection, which makes it an ideal voltage regulator for a wide range of power supply applications.

The working principle of the MIC2211-NNBML-TR is straightforward. Its output voltage is determined by the voltage on two terminals- the Vout (output voltage) terminal and the Vctrl (control voltage) terminal. When the control voltage is above the reference voltage (2.85V), the output voltage is set to 4.7V. When the control voltage is below the reference voltage, the output voltage is set to 0V. This provides excellent regulation and fast response time. The enable pin can be used to enable or disable the IC.

In conclusion, the MIC2211-NNBML-TR is a low-dropout linear voltage regulator that is well-suited for a wide range of low-power applications. It integrates current shunting and current limiting, which together provide excellent system stability and control. Its modest quiescent current and wide input voltage range make it ideal for a variety of low-power applications. The control voltage pin and enable pin provide flexibility in setting the output voltage, and provide protection against current overloads and thermal protection.
