Why is the maximum voltage of the BA3404 (upward-compatible model of the BA2904) ±14V with respect to the maximum output voltage (Low) of 5mV for the BA2904?
The BA3404 is a power supply of ±15V with load resistance of 2kΩ while the BA2904 is a single 5V supply with no-load conditions. From no-load to approx. 40uA, the maximum output voltage of both products will operate up to near VEE.
