My customer met a problem about the REF3325. In our datasheet, the minimum Vin is listed as below:
My question is:
1. What's the difference between the "specified voltage range" and the "operating voltage range". Why the minimum Vin is different?
2. In my customer's case, the Vin of REF3325 is 2.5V and the load current of the REF3325 is 1mA. Customer tested several boards and the REF3325 can output 2.5V. But they wonder is this a reliable condition to generate a 2.5V reference from a 2.5V Vin with 1mA load?
