PMIC (Power Management Integrated Circuit) voltage regulators are an important component for controlling and managing power for critical applications. Power supply control is increasingly being integrated into system design, and small, cost-effective voltage regulator solutions are in high demand. The MP6401DQT-25AD3-LF-P is a dual-channel, low noise, low drop-out linear regulator designed to provide stable, well-regulated voltage supply with very low power dissipation.

Application Field

The MP6401DQT-25AD3-LF-P is ideal for providing stable, low-noise power supply in applications where extremely small size and low power dissipation are essential. Applications include extended battery life products, including medical devices, cellular phones, digital cameras, GPS devices, and other portable electronics.

Working Principle

The MP6401DQT-25AD3-LF-P is a two-channel, low noise, low drop-out linear regulator. It features a low input voltage (down to 1.2 V) and a very small form factor (2.3 x 2.2 mm). The regulator is designed to maintain a constant output voltage regardless of variations in the input voltage, temperature, and load current. The device is able to do this through a feedback loop. The error amplifier senses any variation between the output voltage and a reference voltage, and produces an appropriate output error signal. This signal is then fed back to the current mirror circuit which adjusts the current driving the output stage, thus maintaining a stable output voltage.

The MP6401DQT-25AD3-LF-P incorporates two protection features. The shutdown feature allows the device to be turned off completely to prevent over-loading and thermal runaway. The over-voltage protection feature shuts down the output in case of an over-voltage situation, thus preventing damage to the device. The device also has a wide output voltage range (1.5 V to 7 V) and can operate up to 1.5 A.

The MP6401DQT-25AD3-LF-P is also designed to provide high signal accuracy, low noise, and is ultra-stable. This makes the device ideal for providing high signal accuracy, reliable power supply in small form factor applications such as mobile electronics, digital signal processing, and industrial control systems.

Conclusion

The MP6401DQT-25AD3-LF-P is an ideal solution for providing high signal accuracy, low power dissipation, and stable, low noise power supply in demanding, small form factor applications. The dual-channel, low noise, low drop-out linear regulator design ensures a stable output voltage regardless of variations in input voltage, temperature, and load current, and is protected against over-voltage and thermal runaway. The device is also able to operate from a low input voltage (down to 1.2 V) and offers a wide output voltage range (1.5 V to 7 V).
