General Description

The MAX6001–MAX6005 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.
