Rainbow Electronics MAX6010 User Manual
General Description
The MAX6010 is a precision, low-noise, low-dropout,
micropower voltage reference in a SOT23 package. This
three-terminal voltage reference operates with an input
voltage from 3.2V to 5.5V, and outputs 3V.
The MAX6010 voltage reference consumes less than
5µA (max) of supply current and can source up to 7mA
and sink up to 1mA of load current when the input is
5V. Unlike conventional shunt-mode (two-terminal) references that waste supply current and require an external resistor, the MAX6010 offers a supply current that is
virtually independent of supply voltage (with only
0.05µA/V variation with supply voltage) and does not
require an external resistor. The MAX6010 has initial
accuracies of 0.2% (A grade) and 0.4% (B grade) and
a temperature drift of 50ppm/°C (max). The low-dropout
voltage and the ultra-low supply current over the full
voltage range make this device ideal for portable and
battery-operated applications. The MAX6010 is available in a small, 3-pin SOT23 package.

ABSOLUTE MAXIMUM RATINGS
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
