ON NCV1009D 2.5 volt reference Datasheet

NCV1009
2.5 Volt Reference
The NCV1009 is a precision trimmed 2.5 V ±5.0 mV shunt
regulator diode. The low dynamic impedance and wide operating
current range enhances its versatility. The tight reference tolerance is
achieved by on−chip trimming which minimizes voltage tolerance and
temperature drift.
A third terminal allows the reference voltage to be adjusted ±5.0%
to calibrate out system errors. In many applications, the NCV1009Z
can be used as a pin−to−pin replacement of the LT1009CZ and the
LM136Z−2.5 with the external trim network eliminated.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
