Working Principle

The P9023BR-5AHGI is a linear voltage regulator that operates on the principle of proportional control. It regulates the output voltage by comparing the actual output voltage to the reference voltage, which is set by an external resistive divider. Based on the comparison between the actual output voltage and the reference voltage, the output current is adjusted such that the output voltage maintains a preset equilibrium. In order to reduce switching losses and improve the power efficiency, it has an internal voltage sequence switch that switches between the input and output voltage, resulting in minimization of the voltage difference between the two. The current limit is adjustable to ensure that the device can provide up to 3A of continuous output current, even when subjected to varying load conditions. Furthermore, it features an open-drain output for direct control of an output load, or for powering other devices.
