All discrete component structure, single-stage series voltage regulator design. Without ic use, the entire design can regulate each node of the control loop so that all the performance parameters of the voltage regulator can reach the best state. Complementary regulator structure, the negative regulator part is the complementary mirror image of the positive regulator. Ultra-low noise, high PSRR (power ripple rejection ratio). The low-pass filter's inflection point frequency as low as 1.6Hz prevents diode switching noise from entering the subsequent error amplifier, and this part also has a soft-start function. Effectively guarantees the output noise of the regulated power supply as low as μV Level.
Note: this board only suitable for low current board. such as preamp board. DAC board. headphone amp board etc. are not suitable for high current power amp.
