LHY BATT Lithium Battery Ultra-Low Noise Linear Power Supply

Experience pristine power delivery with this advanced lithium-based linear supply, engineered around the LT3042 topology with integrated PNP current expansion. Achieving ultra-low noise performance at approximately 1μV—substantially superior to traditional regulators—it eliminates AC mains interference entirely. The integrated 4-cell Samsung 21700 battery array (20,000mAh capacity) ensures consistent, artifact-free DC output tailored for discerning applications: high-resolution digital audio transports, precision DAC implementations, sensitive RF instrumentation, and critical measurement equipment. A refined power foundation for uncompromised sonic clarity and operational stability.

Based on the LT3042 chip with PNP current expansion, this unit delivers DC power with near-zero noise (as low as 1μV)—significantly quieter than conventional regulators like LM317/78XX. Powered by 4 Samsung 21700 batteries (20,000mAh total), it provides clean, stable energy free from AC interference, making it ideal for precision instruments, noise-sensitive RF systems, DACs, and digital audio transports. A pure power solution for stable performance and detailed sound.
