Major ripples dealt with by the input capacitor, with residual AC ripples handled by L and output C. ## Pros 1. Low voltage drop across components 2. Low [ripple factor](ripple%20factor.md) 3. High [peak inverse voltage](peak%20inverse%20voltage.md) compared to [L-section filter](L-section%20filter.md) ## Cons Low [voltage regulation](voltage%20regulation.md) because output voltage drops rapidly with current.[^1] --- # References [^1]: [What is Pi Filter? - Working, Characteristics, Advantages, Disadvantages & Applications - Electronics Coach](https://electronicscoach.com/pi-filter.html)
