The architecture features a highly accurate, high-precision, low-noise current reference followed by a state-of-the-art error amplifier (1.1 nV/√Hz at 10-kHz noise for V_OUT ≥ 1.2 V) comparable to, if not better than, that of a precision amplifier. The unity-gain configuration ensures ultra-low noise over the entire output voltage range. Additional noise reduction and higher output current can be achieved by placing multiple TPS7A94 LDOs in parallel.
