CAT8900

Precision Analog Voltage

References

The CAT8900 is a high precision voltage reference providing very

accurate voltage regulation with low supply current consumption.

CAT8900 is ideal for use in battery powered systems where

operating current needs to be minimized and there can be a great

variation in supply voltages. It will source or sink up to 10 mA of load

current, and can for most applications, forgo the use of an output

bypass capacitor. The device is supplied in a space saving three

terminal SOT−23 package.
