All Belleson regulators use the same patented design to deliver super low noise, super high ripple rejection and blazing fast transient response. Which regulator you choose depends on the output voltage you need and how much power the regulator must dissipate. The following product descriptions can help you decide.

SPZ High Current 3A Superpower

SPZ 3A Superpower Regulators, our newest variation on the patented Belleson super regulator design. Small enough to directly replace TO-220 monolithic regulators in most circuits, with better performance.
