19-0458; Rev 1; 9/96
Low-Cost, Micropower, Precision, 3-Terminal,
1.2V Voltage Reference
_______________General Description
The MAX6120 is the lowest-power 1.2V, precision,
three-terminal voltage reference offered in a SOT23
package. Ideal for 3V battery-powered equipment
where power conservation is critical, the MAX6120 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 MAX6120 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 MAX6120 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 typically
only 30ppm/°C, and is guaranteed to be less than
