Working Principle

The MIC5320-KGYML-TR linear voltage regulator (LVR) operates using a simple two-step regulation process. In the first step, the regulator takes the input voltage, typically between 6V and 24V, and reduces it to an intermediate voltage, somewhere between 0V and 5V. This intermediate voltage is then used as the reference voltage for the second step of regulation. In the second step, the regulator compares the intermediate voltage with another reference voltage, typically between 1.37V and 5V depending on the required output voltage. The regulator then adjusts the output voltage to match the comparison voltage.

This two-step approach is known as "series voltage modulation" and is what allows the MIC5320-KGYML-TR LVR to provide the high accuracy and reliable power supply performance that it is known for. By disengaging the P-channel MOSFET during low current consumer, the MIC5320-KGYML-TR is also able to maintain its high efficiency even during changes in input conditions.

Applications

The MIC5320-KGYML-TR is designed for use in a wide variety of applications including smartphones, tablets, home appliances, industrial systems, automotive systems, and more. It is able to provide a reliable, low-cost, and high-performance power solution in the form of a "passive LVR" with no external components required.
