SparkoS SS7918 Voltage Regulator +18V

The SparkoS SS7918 Discrete Voltage Regulator delivers a remarkably clean and stable -18V output, engineered specifically for discerning audio applications where power supply quality directly influences sonic performance. This negative voltage regulator is built from discrete components rather than integrated circuits, offering superior noise characteristics and exceptional ripple rejection that standard regulators cannot match.

Ideal for high-fidelity preamplifiers, headphone amplifiers, digital-to-analogue converters, and other sensitive audio circuits, the SS7918 ensures your signal path remains free from power-induced artefacts. It is particularly suited to dual-rail supply designs where symmetrical, low-noise voltage regulation is critical for maintaining channel balance and stereo imaging. Audiophiles and DIY enthusiasts will appreciate its ability to enhance clarity, detail retrieval, and dynamic range in both new builds and upgrades.

Technically, the SS7918 provides a fixed -18V output with a generous current capability of up to 1 ampere, making it versatile for a wide range of loads. Its discrete topology minimises internal noise sources, while high ripple rejection effectively filters mains-borne interference. The regulator is designed for straightforward integration, with standard pinouts and robust thermal performance ensuring reliable operation under demanding conditions.

For those seeking to elevate their audio system’s power integrity, the SparkoS SS7918 offers a cost-effective upgrade that delivers measurable and audible improvements.
