Overview

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 references.
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 efficiency at all battery voltages.
The MAX6120 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 30ppm/°C, and is guaranteed to be less than 100ppm/°C in the SOT23 package.
For a guaranteed output voltage temperature coefficient of less than 50ppm/°C, see the MAX6520 data sheet.
