Inductance. Usually a much smaller issue than ESR, there is a bit of inductance in any capacitor, which resists changes in current flow. Not a big deal most of the time.
Sometimes the trick is to use ceramic capacitor with series resistance to bring ESR into suitable level. For more info, TI has an appnote AN-1148 for theory of operation and compensation of linear regulators. And forgot to add, yes, a regulator can be observed to become unstable when it does not have correct output (or input) capacitors.

The 100 nF capacitor on the output is an important component for the stability of the regulator''s control loop. It''s not there to catch fast load changes; for that its value is too low. Use an air cooled power resistor in
All of the quantities in the equation are in their standard SI units...volts, amperes, farads, seconds. If the the current is constant then the voltage will decrease linearly. Talking
Understanding the output voltage of a capacitor in an RC (Resistor-Capacitor) circuit is crucial in electronics. resistance, and time are central to many electrical circuits, especially in signal processing and power management. Calculation Formula. The output voltage ( V_{out} ) of a capacitor discharging in an RC circuit is given by the

rms ripple current greatly reduces the power dissipation and increases the life of the bulk input capacitors.

Bulk capacitor power dissipation: P = I2×R
Some controllers rely on a minimum amount of capacitor ESR (Effective Series Resistance) for stability. If you increase capacitor size or add capacitors in parallel the ESR could become too low. For example the LM2575 requires at least 0.05Ω to guarantee stability when running in continuous mode.

7805''s datasheet recommends a 0.33uf and a 0.1uf capacitor for input and output respectively.. For a clean input voltage and a resistive load, I''ve used this kind of regulators without the capacitors and they worked just fine. In cases with a noisy power supply or if there are motors in the circuit this capacitors start getting more relevant but it''s hard for me to get a sense of
The main point here is that the thick black line shows you what the capacitor voltage roughly looks like when there is a real load applied and the capacitor is designed within some range of reason for the load. As the rectified voltage
