Voltage Reference FAQ

Can the LT6657 be configured as a negative voltage reference?

Yes, the high sink current capability allows the device to operate as a negative voltage reference while maintaining the same precision as positive reference operation.

What is the minimum dropout voltage for the 2.5V version?

The LT6657 can be powered from as little as 50mV above the output voltage, allowing for very low dropout operation.
