The MAX6023 voltage references use only 27A of supply current. And unlike shunt-mode (two-terminal) references, the supply current of the MAX6023 family varies only 0.8A/V with supply-voltage changes, translating to longer battery life. Additionally, these internally compensated devices do not require an external compensation capacitor and are stable up to 2.2nF of load capacitance. The low-dropout voltage and the low supply current make these devices ideal for battery-operated systems.
