Power management integrated circuit (PMIC) is a type of integrated circuit (IC) that is combined with multiple functions to manage the power from portable device batteries and power supplies. Incorporated features typically include power regulators, voltage regulators and monitoring functions such as overvoltage protection, overcurrent protection and thermal protection. Voltage regulators are ICs that provide stabilized voltages for different components. Linear voltage regulators work by setting an output voltage and then regulating the voltage so the output voltage is the same and stable. The MIC5397-GPYMT-T5 is an example of a linear voltage regulator.

The MIC5397-GPYMT-T5 is a fully integrated, ultra low-noise, low-quiescent current linear regulator suitable for systems with sensitive analog circuits. It has a power range of 5.0V to 6.5V and can be used to support low power operations with a wide variety of output voltages ranging from 0.8V to 5.0V. The device offers a high output accuracy to within 0.6% and features both overcurrent and overvoltage protection.

The MIC5397-GPYMT-T5 is desirable for its fast transient response and low output voltage slope. The load step response time of the regulator is typically 1.5µs for a load step of 25mA. Its low output voltage slope is essential for optimal noise immunity and allows for faster system wake-up times. Additionally, the regulator can operate from an input voltage range of 2.3V to 6.5V and is capable of supplying up to 400mA of continuous output current.

The operational principle of the MIC5397-GPYMT-T5 is the same as most voltage regulators. An internal error amplifier compares the output voltage to a reference value to generate the corresponding error voltage. This error voltage serves as the input for the control loop which activates an N-MOSFET to limit the current flow. This limits the voltage at the output of the regulator and makes it the same as the reference voltage.

In conclusion, the MIC5397-GPYMT-T5 is a linear voltage regulator suitable for low-power applications with a wide output voltage range. It offers fast transient response and low output voltage slope, meaning that systems can reach the desired output voltage quickly with minimal noise. The MIC5397-GPYMT-T5 is a reliable and cost-effective solution for applications requiring a high accuracy and low noise voltage regulator.
