Typical Circuit Diagram and Analysis of 3.3V Voltage Regulator

by

The role of the capacitor in the 3.3V voltage regulator circuit Generally speaking, the input capacitor of a 3.3V voltage regulator chip is for filtering, while the output capacitor is to prevent oscillation and maintain voltage regulation performance. However, this is not an absolute rule; as chip designs improve and processes become more sophisticated, some … Read more
