MAX6120 - 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.

MAX6120 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.
