About the Product

BA1U 0.8V LDO Chip for Antminer Hash Boards

The BA1U 0.8V LDO (Low Dropout) Regulator is used on modern Antminer hash boards including S21, T21, L7, S19XP and S19j Pro. It stabilizes low-voltage rails to ensure reliable ASIC operation, reducing voltage fluctuations and improving long-term mining stability.

Stable Low-Voltage Regulation for Professional Mining Hardware

With an input voltage range of 1.6V to 5.5V and fixed 0.8V output, the BA1U chip meets the strict power requirements of high-density ASIC hash boards. Its low output noise, high PSRR and protection features make it suitable for demanding 24/7 mining environments.

Key Features

  • Low output noise and low dropout voltage
  • Thermal overload and current limit protection
  • High PSRR (74dB at 1 kHz)
  • Rated output current: 500 mA
  • Fast output discharge function
  • Commonly paired with BA2X in Antminer power rails
