5 Low VCC Guidance

The minimum VCC for this device family is 3 V and many applications use a 5-V supply with good results. For lower supply voltages, such as those in the range of 3 V to 3.6 V, pay careful attention to the input and output voltage ranges. Note that these are especially limited at the device's lowest operating temperature. For more information on this topic and device family, please consult the General Purpose Amps at Low Voltage blog.
