Arcade power supplies are critical for ensuring stable and reliable operation of arcade machines. Voltage regulation is a key feature, preventing damage from fluctuations and maintaining consistent performance. The most common types of voltage regulation in arcade power supplies include:

1. Linear Regulators: These provide simple and low-noise voltage regulation by dissipating excess power as heat. They are reliable but less efficient for high-current applications.

2. Switching Regulators: More efficient than linear regulators, these use high-frequency switching to adjust voltage levels, making them ideal for power-hungry arcade systems.

3. Zener Diode Regulation: Often used for low-power applications, Zener diodes maintain a fixed voltage by shunting excess current.

4. Buck/Boost Converters: These adjust input voltage to a higher or lower level, ensuring compatibility with different arcade components.

Understanding these regulation methods helps in selecting the right power supply for optimal arcade machine performance.
