Working Principles

The REF02APG4 is based on a bandgap voltage reference circuit, which generates a stable and accurate voltage reference using a combination of bipolar and CMOS technologies. The bandgap circuit compensates for temperature variations, ensuring consistent performance over a wide temperature range. The output voltage is proportional to the input voltage and remains stable under varying loads.
