The PowerReg is a dual power regulator using the SKA topology to achieve a very high quality regulated +/- DC supply for power amplifiers such as the GB150D or GB300D. The performance is, unlike most integrated op-amp based power regulators, capable of maintaining the peak performance right out to 20KHz. It uses a pair of 150W MOSFET
pass devices on each supply that require adequate heatsinking.

It is capable of powering one or two (8 ohm drive) GB150Ds or one GB300D
