The MAX6520ESA 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 MAX6520ESA is a low-power alternative to existing two-terminal shunt references. Unlike two-terminal references that throw away battery current and require an external series resistor, the MAX6520ESA has a 70μA maximum supply current (typically only 50μA) that is independent of the input voltage. This feature translates to maximum efficiency at all battery voltages. The MAX6520ESA operates from a supply voltage as low as 2.4V, and initial accuracy is ±1% for the SOT23 package. Output voltage temperature coefficient is typically only 25ppm/°C, and is guaranteed to be less than 50ppm/°C in the SOT23 package.
