This paper proposes a capacitor-free Flipped Voltage Follower (FVF) Low Dropout (LDO) regulator. To stabilize the feed-back loop, the proposed multi-stage FVF LDO regulator does not require a Miller compensation capacitor or physical resistor. A capacitor-free internal structure improves closed-loop bandwidth while saving area in the LDO regulator.

Different applications have different performance requirements and demand capacitors with specific characteristics. The power dissipated by a capacitor is a function of ripple current and equivalent series resistance. As such, the ripple current capability is one of the key parameters to consider when selecting a capacitor for a specific ...
2. The upper (and lower) blue arrows in the two circuits point in opposite directions. This is done to show that, in real time (when they''re in the same circuit together), their actions are exactly opposite one another – so, for example, when the inductor is removing energy from its circuit, the capacitor is returning energy to its circuit and vice versa.
Capacitor discharge voltage curve (top) and capacitor current (bottom). The negative current is because current is leaving the capacitor. Image source: Electronics-Tutorials. The concept of time constant is useful in RC or RL circuits. In the case of the RC discharge it is the time taken to discharge by 63% from an initial value and is assigned the Greek letter tau, τ, …

Anything downstream of a large capacitor will need to have significant Power Supply Rejection Ratio (PSRR) to cope with the ripple. There are cheaper ways of improving this by a factor of two than doubling the size of the Big Filtering Capacitor (BFC).
