Voltage Reference FAQ

What is the minimum input voltage required for stable operation?

The minimum input voltage is VOUT + 0.5V, provided the supply does not exceed 36V.

Can this device operate as a negative voltage reference?

Yes, by connecting the output to a negative rail and biasing the internal circuitry with a positive voltage at VIN through a current-limiting resistor.
