AI Customer ServiceTo ensure stability, a compensation capacitor can be added to increase either C1 or C2, thereby creating a pole dominant over p1. Unfortunately, p2 and p3 are formed by low impedance nodes, necessitating a compensation capacitance on the order of CP. For example, to ensure stability with C2, inequality (14) must be satisfied. 2 ! ̈ ̈ 2 A RB · 4.
Objective of compensation is to achieve stable operation when negative feedback is applied around the op amp. Miller - Use of a capacitor feeding back around a high-gain, inverting stage.

Since the pole ratio needs to be very large, CC gets very large ! Thus, a large effective capacitance can be created with a much smaller capacitor if a capacitor bridges two nodes with a large inverting gain !! ZIN =? Compensation capacitance reduced by approximately the gain of the second stage!
There is no one-size fits all answer. But large capacitors can affect the stability of op-amps or switching regulators. And they can give rise to large inrush currents when power is first connected to a circuit.
When looking at capacitance several different sources say that circuits might malfunction or burn with higher capacity capacitors than designed with. Unfortunately, but none of those sources go into detail. How can a capacitor cause malfunction if capacitance increases? Wouldn't the capacitor simply take longer to fully charge?
