The MAX6120 is the lowest-power 1.2V, precision, three-terminal voltage reference offered in a SOT23 package.
The MAX6120 is a micropower, precision voltage reference designed for battery‑powered equipment. It operates from 2.4 V to 11 V supply voltage, draws only 50 µA typical current independent of input voltage, and provides a stable 1.2 V output with ±1 % initial accuracy.
Typical specifications include a 30 ppm/°C temperature coefficient, operation from –40 °C to +85 °C, and a maximum supply current of 70 µA. The device is offered in a 3‑pin SOT‑23 package and can be used without an output decoupling capacitor, though a small load capacitor (≤10 nF) may be added if needed.
| Typical Supply Current | 50 µA |
|---|---|
| Maximum Supply Current | 70 µA |
| Input Voltage Range | 2.4 V to 11 V |
| Output Voltage | 1.2 V |
| Temperature Coefficient | 30 ppm/°C (typical) |
| Initial Accuracy | ±1 % |
| Operating Temperature Range | -40 °C to +85 °C |
The MAX6120 typically draws 50 µA of supply current.
It operates with an input voltage from 2.4 V up to 11 V.
The typical temperature coefficient is 30 ppm/°C, guaranteed to be less than 100 ppm/°C in the SOT‑23 package.
The MAX6120 performs well without an output decoupling capacitor, but if one is used the total load should not exceed 10 nF.
