BATT | Lithium Battery Ultra-Low Noise Linear Power Supply

Description

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.

Core Technical Features


1. Ultra-Low Noise Power Output

  • Incorporates Linear Technology's premium LT3042 regulator with PNP current boost
  • Achieves noise voltage as low as 1μV - 2-3 levels better than conventional LM317/LM78XX regulators
  • 1% voltage accuracy for near-zero noise DC power supply


2. High-Performance Battery System

  • Equipped with 4 Samsung 21700 lithium cells (5000mAh each)
  • Superior volumetric energy density compared to standard lithium batteries
  • Battery power completely isolates AC line interference for purest power


3. Audio-Optimized Performance

  • Clean power delivery dramatically improves sound quality
  • Eliminates high-frequency harshness caused by current noise
  • Expands dynamic range for more stable musical presentation
  • Enhances detail retrieval and creates more realistic soundstage

Recommended Applications:

  • High-precision measurement instruments
  • Noise-sensitive RF applications
  • DAC audio converters
  • USB interface devices
  • Digital music transports
  • Professional mobile power requirements
