Ultra-Low-Noise LDO Achieves 6nV/√Hz Noise Performance
Abstract: This ultra-low-noise LDO combines low-noise components with filtering to achieve an output noise performance of 6nV/√Hz
at 1kHz.

This design idea appeared in the June 23, 2005 issue of EDN . Of the many low-dropout (LDO) regulators used to regulate voltage in
electronic systems, some are specifically designed for low-noise operation. The MAX8887
