The MAX6018 is a precision, low-voltage, low-dropout,
micropower voltage reference in a SOT23 package. This
three-terminal reference operates with an input voltage
from (V
put voltage options of 1.2V, 1.6V, 1.8V, and 2.048V
The MAX6018 voltage reference consumes less than
5µA (max) of supply current and can source and sink
up to 1mA of load current. Unlike conventional shunt-
mode (two-terminal) references that waste supply cur-
rent and require an external resistor, devices in the
MAX6018 family offer a supply current that is virtually
independent of supply voltage (with only 0.1µA/V varia-
tion with supply voltage) and do not require an external
resistor. The MAX6018 has initial accuracies of 0.2% (A
grade) and 0.4% (B grade) and temperature drift of
50ppm/°C (max). The low-dropout voltage and the
ultra-low, supply voltage-independent supply current
make this device ideal for two-cell alkaline, end-of-life,
battery-monitoring systems. The MAX6018 is available
in a tiny 3-pin SOT23 package.
