A.1.2. Current requirements

Table A.2 shows current requirements measured at room temperature and nominal voltage.

The power regulators are all powered from the 5V supply. The maximum current drawn from this supply is 3A. The maximum current requirements for the individual supplies are listed in Table A.2. Interface logic, the ADC, and the on board SDRAM memory are powered directly from the 3V3 supply.
