MIC94345-FYMT-TR Application Field and Working Principle

The MIC94345-FYMT-TR is a low-drop-out (LDO) linear voltage regulator and is classified as part of power management integrated circuits (PMIC) more specifically, as part of voltage regulators linear PMIC solutions.

Application Fields

The MIC94345-FYMT-TR linear voltage regulator is designed for many different applications such as mobile computing, embedded system, automotive and industrial products. As this linear voltage regulator is fixed, it has a total output voltage of 3.3V and it has an input voltage range between 1.8V and 5V with an output current of up to 1A.

The MIC94345-FYMT-TR also offers better power-supply transient response and fast transients. With its low quiescent current of 12 μA, it is also suitable for battery-operated or energy-harvesting applications. Additionally, this linear voltage regulator is RoHS (Restriction of Hazardous Substances) compliant and halogen-free, making it suitable for industrial and automotive designs.

Working Principle

As the MIC94345-FYMT-TR is a linear voltage regulator, it works by creating a constant output voltage from an input voltage that is usually higher than the required output voltage. This is done through a linear-equalizing process, where a variable resistor and a voltage reference circuit work together. The variable resistor is designed in a way that when the input voltage is higher than the output voltage, it reduces the amount of current that is flowing to the output.

The linear voltage regulator takes the input voltage and passes it through the voltage reference circuit. The voltage reference circuit is a set of resistors that produces a reference voltage. The reference voltage is then compared to the input voltage and if the input voltage is greater than the reference voltage a signal is sent to the variable resistor. The variable resistor then reduces the amount of current flowing to the output, thus producing a constant output voltage.

The MIC94345-FYMT-TR also includes active-high enable control. This allows the user to control when the regulator is on or off by using an external control signal, thus optimizing efficiency and power consumption.

Conclusion

The MIC94345-FYMT-TR is a low-drop-out (LDO) linear voltage regulator that is designed for many different applications such as mobile computing, embedded system, automotive and industrial products due to its low quiescent current of 12 μA. It operates by creating a constant output voltage from an input voltage that is usually higher than the required output voltage through a linear-equalizing process, where a variable resistor and a voltage reference circuit work together. The MIC94345-FYMT-TR also includes active-high enable control for the user to control when the regulator should be on or off.
