The MAX6520 is the lowest-power 1.2V, precision,

three-terminal voltage reference offered in a SOT23-3

package. Ideal for 3V battery-powered equipment

where power conservation is critical, the MAX6520 is a

low-power alternative to existing two-terminal shunt ref-

erences. Unlike two-terminal references that throw

away battery current and require an external series

resistor, the MAX6520 has a 70µA maximum supply

current (typically only 50µA) that is independent of the

input voltage. This feature translates to maximum effi-

ciency at all battery voltages.

The MAX6520 operates from a supply voltage as low as

2.4V, and initial accuracy is ±1% for the SOT23 pack-

age. Output voltage temperature coefficient is typi-

cally only 25ppm/°C, and is guaranteed to be less

than 50ppm/°C in the SOT23 package.
