General Description
The MAX6001MAX6005 family of SOT23, low-cost
series voltage references meets the cost advantage of
shunt references and offers the power-saving advantage
of series references, which traditionally cost more. Unlike
conventional shunt-mode (two-terminal) references that
must be biased at the load current and require an exter-
nal resistor, these devices eliminate the need for an
external resistor and offer a supply current that is virtually
independent of the supply voltage.
These micropower, low-dropout, low-cost devices are
ideal for high-volume, cost-sensitive 3V and 5V battery-
operated systems with wide variations in supply voltage
that require very low power dissipation. Additionally,
these devices are internally compensated and do not
require an external compensation capacitor, saving
valuable board area in space-critical applications.

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.
