Datasheet Analog Devices MAX6018

MAX6018 Precision, Micropower, 1.8V Supply,
Low-Dropout, SOT23 Voltage Reference General Description 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 (VOUT + 200mV) to 5.5V, and is available with output
voltage options of 1.2V, 1.6V, 1.8V, and 2.048V Benefits and Features ●● Ultra-Low Supply Current: 5μA (max)
●● 1.6V Output from 1.8V Input
●● Ultra-Small, 3-Pin SOT23 Package
●● Initial Accuracy: ±0.2% (max) 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 current 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 variation 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 voltageindependent 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. ●● Low Temperature Drift: 50ppm/°C (max) Applications
