are not unusual, which means the LDO ground pin current can be as high as 7% of the load current. A big advantage of NPN regulators is that they are unconditionally stable (most require no external capacitors). An LDO does require at least one external capacitor on the output to reduce the loop bandwidth and provide some positive phase shift.

The comparison between Figs. 13.25(b) and 13.27(b) shows how changing from (30-pF) compensation to compensation that includes a zero can greatly improve stability and can reduce settling time by more than a factor of 10 for a capacitively loaded voltage follower.
A capacitor bank is a group of several capacitors of the same rating that are connected in series or parallel to store electrical energy in an electric power system.Capacitors are devices that can store electric charge by creating an electric field between two metal plates separated by an insulating material. Capacitor banks are used …
$begingroup$ The voltage regulator cannot respond instantaneously to changes in power requirements, resulting in a momentary dip in voltage when current demands increase. The capacitors charge to the output voltage level of the regulator, and then supply localized current while the regulator adjusts to meet the demands on the power rail.
