MP6401DQT-33BD3-LF-P Working Principle

At its most basic, the MP6401DQT-33BD3-LF-P follows the standard linear voltage regulator topology. The device takes a single input voltage (Vin) and regulates it to a predetermined output voltage (Vout) before outputting the resulting adjustable regulated voltage through the output pin (VLP). The device achieves this regulation by internally converting the difference between the input voltage and the set output voltage into a current and then drawing it away from the output pin via a pass element. The current is then dissipated as heat to complete the regulation process.

The MP6401DQT-33BD3-LF-P additionally provides adjustable current limit protection, reverse current protection, and dynamic over temperature protection while maintaining low quiescent current operation. All of these features make the MP6401 a great choice for battery powered applications that require low dropout performance, low noise output and high efficiency.

Conclusion

The MP6401DQT-33BD3-LF-P is a versatile high-performance linear voltage regulator that is ideal for low voltage battery-powered systems, such as digital still and video cameras, portable video display systems, as well as intelligent devices and HMI. The device offers a wide adjustable output voltage range of 1.2V to 4.77V, and provides reverse discharge protection, adjustable current limit protection and dynamic over temperature protection.
