Low-Cost, Micropower, Precision, 3-Terminal, 1.2V Voltage Reference MAX6120 _______________General Description ____________________________Features
The MAX6120 is the lowest-power 1.2V, precision, ♦
3-Pin SOT23 Package
three-terminal voltage reference offered in a SOT23 package. Ideal for 3V battery-powered equipment ♦
Supply Current Independent of Input Voltage
where power conservation is critical, the MAX6120 is a
Over Temperature
low-power alternative to existing two-terminal shunt ref- erences. Unlike two-terminal references that throw ♦
50µA Supply Current
away battery current and require an external series resistor, the MAX6120 has a 70µA maximum supply ♦
2.4V to 11V Input Voltage Range
current (typically only 50µA) that is independent of the ♦

input voltage. This feature translates to maximum effi- ciency at all battery voltages. ♦
±1% Initial Accuracy (SOT23)
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
