    Hello,

    I wish to use the MCP1703 voltage regulator to produce a 3V reference voltage from a 3.3V rail.
    (it will provide the reference voltage for a microcontrollers ADC reference input)
    What is the minimum load current that i need to load the output with in order to get the output voltage accurate at 3V?
    The datasheet graphs seem to show a minimum current of 1mA flowing.
    What will the accuracy be like if only 100uA flows?
