ONSEMI CAT8900C300TBIT3

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.
