Working Principle

The MIC5201-5.0BS voltage regulator is a linear regulator, meaning it regulates the output voltage by adjusting the input voltage through an internal pass transistor, which controls the line regulation and load regulation of the device. The voltage regulation is achieved by the feedback loop, which compares the output voltage to an internal reference voltage, and adjusts the current input to the pass transistor accordingly, so as to maintain the output voltage. This process is known as a voltage regulating cycle.

In order to provide high efficiency and reliability, the MIC5201-5.0BS voltage regulator is designed with a two-phase oscillator system. The two-phase oscillator system is a standard method to keep the input voltage regulated. It works by controlling the current passing through the pass transistor, which in turn determines the output voltage. The two-phase oscillator system continuously monitors and adjusts the voltage-regulating cycle so as to keep the output voltage within an acceptable range.
